SAFETY PRECAUTIONS
!
!
!
!
!
Read this manual and all safety precautions before attempting to operate your
WerkMaster Scarab. Failure to follow the safety precautions could result in
electric shock, fire and/or serious injury.
The term “variable speed grinder/polisher” refers to your main-operated (corded)
power tool or battery operated (cordless) power tool. ALWAYS refer to the
variable speed grinder/polisher manual when using the Scarab.
!
!
•Wear eye and ear protection at all times when operating WerkMaster
machines. Use only ANSI/OSHA approved safety glasses to help
prevent eye injury.
•Wear appropriate clothing and footwear when operating WerkMaster
machines. Do not wear loose clothing or jewelry that can become
entangled in moving parts.
•Safety equipment such as dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate conditions will reduce
personal injuries.
•Avoid accidental starting. Ensure the switch is in the OFF position before
plugging in. Do not carry power tools with your finger on the switch or
plug in power tools that have the switch on.
•Remove any adjusting key or wrench before turning the power tool on. A
wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
•Do not overreach. Keep proper footing and balance at all times.
•Always use a vacuum. Ensure the variable speed grinder/polisher is
properly connected to the Scarab and follow all operating procedures.
•Keep handles dry, clean and free from oil and grease.
!
•Never operate WerkMaster machines under the influence of drugs or
alcohol, when taking medications that impair the senses or reactions, or
when excessively tired or under stress.
!
•WerkMaster machines are designed to be operated by one person at a
time. Maintain a safe operating distance to other persons. Keep
bystanders a safe distance away during operation by blocking off the
work area in all directions with roping, safety netting, or other material.
Failure to do so may result in someone being injured by flying debris or
being exposed to harmful dust and noise.
•Maintain a safe operating distance from flammable materials. Sparks
from the cutting action of WerkMaster machines may ignite flammable
materials or vapors.

!
!
•Keep work area clean and well lit.
•Turn off the WerkMaster before disconnecting power.
•DO NOT disconnect power by pulling the cord. To disconnect power,
grasp the plug, not the cord. To remove twist-lock plugs, push in and
turn clockwise to engage, and turn counter-clockwise and pull to
remove.
!
•ALWAYS refer to the variable speed grinder/polisher manual for safe
operation
•DO NOT let comfort or familiarity with this tool (gained from repeated
use) replace strict adherence to polisher safety rules. If you use this tool
unsafely or incorrectly, you may suffer serious personal injury.
•Running accessories over rated speeds may cause injury.
•Firmly secure any loose surface before operating the Scarab. Do not use
your hand or body to secure loose surfaces.
•Hold the tool firmly with both hands. Do not drop. When using either
the handheld handle, or the full extension articulating handle assembly,
be sure to keep the Scarab level or flat with the surface, using smooth
and continuous movement. Avoid objects projecting out of the solid
surface you are working on as they may cause damage to the tooling.
•Keep hands away from rotating parts.
•When sanding metallic surfaces, the operator should watch for
flying sparks. Hold the tool so that the sparks fly away from you, other
persons and flammable materials.
•DO NOT leave the tool running.
•DO NOT touch the work surface immediately after operation; it may be
hot.
•Pay attention; the Plug ‘N Go tooling plates may continue to rotate after
the tool is switched off.
•Ventilate your work area adequately when operating a Scarab.
•Use of this tool to sand or grind could expose user to dust containing
hazardous substances. Use appropriate respiratory protection.
!
•DO NOT modify WerkMaster machines. Modifications will void the
warranty and may result in injury to persons and damage to the
machine.

edge right to the wall.
3. As a safety measure, when removing a section of the dust skirt in order to
run the machine right to the wall keep the open section away from operator.
