INTRODUCTION
e Wet Polisher has many features
for making the use of this tool more
pleasant and enjoyable. Safety, perfor-
mance, and dependability have been
given top priority in the design of this
polisher making it easy to maintain
and operate.
GENERAL SAFETY RULES
Read all instructions. Failure to fol-
low all instructions listed below may
result in electric shock, re and/or se-
rious injury. e term “power tool”
in all of the warnings listed below re-
fers to your variable speed wet pol-
isher.
WORK AREA
• Keep your work area clean and
well lit. Cluttered benches and dark
areas invite accidents.
• Do not operate power tools in ex-
plosive atmospheres, such as in the
presence of ammable liquids, gases,
or dust. Power tools may create sparks
that may ignite the dust or fumes.
• Keep bystanders, children, and visi-
tors away while operating a power
tool. Distractions can cause you to
lose control.
ELECTRICAL SAFETY
• Power tool plugs must match
the outlet. Never modify the plug
in any way. Do not use any adapt-
er plugs with grounded power tools.
Unmodied plugs and matching out-
lets will reduce risk of electric shock.
• Avoid body contact with ground-
ed surfaces, such as pipes, radiators,
ranges, and refrigerators. ere is an
increased risk of electric shock if your
body is grounded.
• Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an out-
let. Keep cord away from heat, oil, sharp edg-
es, or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk
of electric shock.
ELECTRICAL SAFETY
• When operating a power tool outside use
an outdoor extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use re-
duces the risk of electric shock.
• Make sure your extension cord is in
good condition. When using an extension
cord, be sure to use one heavy enough to carry
the current your product will draw. An un-
dersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
PERSONAL SAFETY
• Stay alert, watch what you are doing and
use common sense when operating a power
tool.Do not use tool while tired or under the
inuence of drugs, alcohol, or medica- tion. A
moment of inattention while operating power
tools may result in serious personal injury.
• Use safety equipment. Always wear eye pro-
tection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing
protec- tion used for appropriate conditions
will reduce the risk of personal injury.
• Avoid accidental starting. Ensure the
switch is in the o position before plugging
in. Carrying power tools with your nger
on the switch or plugging in power tools that
have the switch on invites accidents.
• Remove any adjusting keys or wrenches
before turning the tool on. A wrench or a key
that is left attached to a rotating part of the
tool may result in personal injury.
• Do not overreach. Keep proper footing and
balance at all times. is enables better con-
trol of the power tool in unexpected situations.
• Dress properly. Do not wear loose
clothing or jewelry. Keep your hair
clothing and gloves away from mov-
ing parts. Loose clothes, jewelry or
long hair can be caught in moving
parts.
• If devices are provided for the con-
nection of dust extraction and collec-
tion facilities, ensure these are con-
nected and properly used. Use of
these devices can reduce dust related
hazards.

ishing speed. Excessive pressure will
overload the motor causing possible
damage from overheating.
