Unmodified plugs and matching out-  
lets will reduce risk of electric shock.  
tion. Safety equipment such as dust  
mask, non-skid safety shoes, hard  
hat, or hearing protection used for  
appropriate conditions will reduce  
personal injuries.  
b.Avoid body contact with grounded  
surfaces such as pipes, radiators,  
ranges and refrigerators. There is  
an increased risk of electric shock if  
your body is grounded.  
c.Keep guards in place and in good  
working order.  
d.Prevent unintentional starting.  
Ensure the switch is in the off-po-  
sition before connecting to power  
source and/or battery pack, pick-  
ing up or carrying the tool. Carry-  
ing power tools with your finger on  
the switch or energizing power tools  
that have the switch on invites acci-  
dents.  
c.Do not expose power tools to rain  
or wet conditions. Water entering  
a power tool will increase the risk of  
electric shock.  
d.Do not abuse the cord. Never use  
the cord for carrying, pulling or  
unplugging the power tool. Keep  
cord away from heat, oil, sharp  
edges or moving parts. Damaged  
or entangled cords increase the risk  
of electric shock.  
e.Remove any adjusting key or  
wrench before turning the power  
tool on. A wrench or a key left at-  
tached to a rotating part of the power  
tool may result in personal injury.  
e.When operating a power tool out-  
doors, use an extension cord suit-  
able for outdoor use. Use of a cord  
suitable for outdoor use reduces the  
risk of electric shock.  
f. Do not overreach. Keep proper  
footing and balance at all times.  
This enables better control of the  
power tool in unexpected situations.  
f. If operating a power tool in a damp  
location is unavoidable, use a  
Ground Fault Circuit Interrupter  
(GFCI) protected supply. Use of  
a GFCI reduces the risk of electric  
shock.  
g.Dress properly. Do not wear loose  
clothing or jewelry. Keep your  
hair, clothing and gloves away  
from moving parts. Loose clothes,  
jewelry or long hair can be caught in  
moving parts.  
3. Personal safety  
h.If devices are provided for the con-  
nection of dust extraction and col-  
lection facilities, ensure these are  
connected and properly used. Use  
of these devices can reduce dust-  
related hazards.  
a.Stay alert, watch what you are do-  
ing and use common sense when  
operating a power tool. Do not use  
a power tool while you are tired  
or under the influence of drugs,  
alcohol or medication. A moment  
of inattention while operating power  
tools may result in serious personal  
injury.  
4. Power tool use and care  
a.Do not force the power tool. Use  
the correct power tool for your ap-  
plication. The correct power tool will

do the job better and safer at the rate  
for which it was designed.  
ent from those intended could result  
in a hazardous situation.  
b.Do not use the power tool if the  
switch does not turn it on and off.  
Any power tool that cannot be con-  
trolled with the switch is dangerous  
and must be repaired.  
5. Service  
a.Have your power tool serviced by  
a qualified repair person using  
only identical replacement parts.  
This will ensure that the safety of the  
power tool is maintained.  
c.Disconnect the plug from the  
power source and/or the battery  
pack from the power tool before  
making any adjustments, chang-  
ing accessories, or storing power  
tools. Such preventive safety mea-  
sures reduce the risk of starting the  
power tool accidentally.  
Vibration Safety  
This tool vibrates during use. Re-  
peated or long-term exposure to  
vibration may cause temporary or  
permanent physical injury, particularly  
to the hands, arms and shoulders. To  
reduce the risk of vibration-related  
injury:  
d.Store idle power tools out of the  
reach of children and do not allow  
persons unfamiliar with the power  
tool or these instructions to oper-  
ate the power tool. Power tools are  
dangerous in the hands of untrained  
users.  
1. Anyone using vibrating tools regu-  
larly or for an extended period should  
first be examined by a doctor and  
then have regular medical check-  
ups to ensure medical problems are  
not being caused or worsened from  
use. Pregnant women or people  
who have impaired blood circulation  
to the hand, past hand injuries, ner-  
vous system disorders, diabetes, or  
Raynaud’s Disease should not use  
this tool. If you feel any medical or  
physical symptoms related to vibra-  
tion (such as tingling, numbness, and  
white or blue fingers), seek medical  
advice as soon as possible.  
e.Maintain power tools. Check for  
misalignment or binding of moving  
parts, breakage of parts and any  
other condition that may affect the  
power tool’s operation. If dam-  
aged, have the power tool repaired  
before use. Many accidents are  
caused by poorly maintained power  
tools.  
f. Keep cutting tools sharp and  
clean. Properly maintained cutting  
tools with sharp cutting edges are  
less likely to bind and are easier to  
control.  
2. Do not smoke during use. Nico-  
tine reduces the blood supply to the  
hands and fingers, increasing the risk  
of vibration-related injury.  
g.Use the power tool, accessories  
and tool bits etc. in accordance  
with these instructions, taking into  
account the working conditions  
and the work to be performed. Use  
of the power tool for operations differ-  
3. Wear suitable gloves to reduce the  
vibration effects on the user.

Saw if the Blade Guard does not  
move freely. Make sure the Blade  
Guard moves freely and does not  
touch the Saw Blade or any other  
part of the Saw, in all angles and  
depths of cut.  
5. Include vibration-free periods each  
day of work.  
6. Grip tool as lightly as possible (while  
still keeping safe control of it). Let  
the tool do the work.  
7. Do not handle the Power Switch  
(21) with wet hands.  
7. To reduce vibration, maintain the tool  
as explained in this manual. If any  
abnormal vibration occurs, stop use  
immediately.  
8. Make sure the Tile Saw is located  
on a flat, level, sturdy surface ca-  
pable of supporting the weight of  
the Saw and work pieces.  
9. Always use 67393 7” Continu-  
ous Rim Diamond Saw Blade (not  
included, sold separately) with a 1”  
round arbor hole, and rated at 3565  
RPM or greater.

DRIP LOOP  
Figure 1  
14. Always arrange a “drip loop” in the  
Power Cord/Plug (34) connecting  
the Tile Saw to a 120 volt, ground-  
ed, electrical outlet. A drip loop is  
that part of the Power Cord below the  
level of the outlet, or the connector  
if an extension cord is used, to pre-  
vent water traveling along the Power  
Cord and coming in contact with the  
outlet. If the Power Plug or electrical  
outlet does get wet, do not unplug the  
Power Cord. Disconnect the fuse or  
circuit breaker that supplies power to  
the tool. Then, unplug and examine  
for presence of water in the outlet.

sure the Saw Blade is balanced, and  
is not cracked or bent.  
23. The Saw Blade will become hot  
while cutting. Allow Blade to com-  
pletely cool before handling.  
24. Allow the Saw Blade to spin up to  
full speed before feeding a work  
piece into it. When turning off the  
Tile Saw, allow the Saw Blade to spin  
down and stop on its own. Do not  
press against the Saw Blade to stop  
it.  
15. Use cold water only. Never use  
hot water.  
16. Never run the Tile Saw without a  
water supply. Running the unit with-  
out a water supply will cause irrepa-  
rable damage.  
25. Do not force workpiece onto the  
Saw Blade. Apply moderate pres-  
sure, allowing the Saw Blade to cut  
without being forced.  
17. Make sure the water supply used  
for the Tile Saw is not dirty, sandy,  
and does not contain any corro-  
sive chemicals.  
26. Turn off the Tile Saw and allow it  
to stop on its own if the Blade is to  
be backed out of an uncompleted  
cut.  
18. Make sure to change the water

erly supported. If necessary, use a  
roller stand (not included) with larger  
work pieces.  
37. Always turn off the Tile Saw and  
unplug it from its electrical outlet  
before changing accessories or  
performing any inspection, mainte-  
nance, or cleaning procedures.  
29. Never lean on the Tile Saw. Seri-  
ous injury could result if the Tile Saw  
is tipped or if the rotating Saw Blade  
is accidently contacted.  
38. WARNING! Some dust created  
by power sanding, sawing, grind-  
ing, drilling, and other construction  
activities, contain chemicals known  
(to the State of California) to cause  
cancer, birth defects or other repro-  
ductive harm. Some examples of  
these chemicals are: lead from lead-  
based paints, crystalline silica from  
bricks and cement and other masonry  
products, arsenic and chromium from  
chemically treated lumber. Your risk  
from these exposures varies, depend-  
ing on how often you do this type of  
work. To reduce your exposure to  
these chemicals: work in well venti-  
lated areas, and work with approved  
safety equipment such as those dust  
masks that are specially designed to  
filter out microscopic particles.  
30. Industrial applications must follow

OPERATING INSTRUCTIONS  
Read the ENTIRE IMPORTANT  
SAFETY INFORMATION section  
at the beginning of this manual  
including all text under  
subheadings therein before set  
up or use of this product.  
6. Maintain tools with care. Keep  
tools clean. Properly maintained  
tools are easier to control. Do not  
use a damaged tool. Tag damaged  
tools “Do not use” until repaired.  
Tool Set Up  
7. Check for misalignment or binding  
of moving parts, breakage of parts,  
and any other condition that may  
affect the tool’s operation. If dam-  
aged, have the tool serviced before  
using. Many accidents are caused  
by poorly maintained tools.  
TO PREVENT  
SERIOUS INJURY  
FROM ACCIDENTAL  
OPERATION: Turn the Power  
Switch of the tool to its “OFF”  
position and unplug the tool  
from its electrical outlet  
before performing any  
inspection, maintenance, or  
cleaning procedures.  
8. Use only accessories that are  
recommended by the manufacturer  
for your tool. Accessories suitable  
for one tool may become hazardous  
when used on another tool.  
1. Use Clamping Plate (56) to secure  
and support smaller work pieces to  
the built-in fence. Holding work by  
hand or against your body is unstable  
and may lead to loss of control.  
Work Piece and Work Area Set Up  
1. Designate a work area that is clean  
and well lit. The work area must not  
allow access by children or pets to  
prevent injury and distraction.  
2. Do not force tool. Use the cor-  
rect tool for your application. The  
correct tool will do the job better and  
safer at rate for which it is designed.  
2. Route the power cord along a safe  
route to reach the work area with-  
out creating a tripping hazard or  
exposing the power cord to pos-  
sible damage. The power cord must  
reach the work area with enough  
extra length to allow free movement  
while working.  
3. Do not use the power tool if the  
Power Switch does not turn it on  
or off. Any tool that cannot be con-  
trolled with its Power Switch is dan-  
gerous and must be replaced.  
4. Disconnect Power Cord Plug from  
the power source before making  
any adjustments, changing acces-  
sories, or storing the tool. Such  
preventive safety measures reduce  
risk of starting the tool accidentally.  
3. Secure loose work pieces using  
clamps (not included) to prevent  
movement while working.
