before making any adjustments, changing 
accessories, or storing power tools. 

Such 

preventive safety measures reduce the risk of 
starting the power tool accidentally. 

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 operate the power tool. 

Power tools are 

dangerous in the hands of untrained users. 

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 damaged, 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. 

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 different from those intended 
could result in a hazardous situation. 

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.

SAFETY INSTRUCTIONS FOR 

ALL OPERATIONS

SAFETY WARNINGS COMMON FOR GRINDING, 
SANDING, WIRE BRUSHING, POLISHING OR 
ABRASIVE CUTTING-OFF OPERATIONS:
a)  This power tool is intended to function as a grinder, 

sander, wire brush, polisher or cut-off tool.  Read 
all safety warnings, instructions, illustrations and 
specifications provided with this power tool.

 Failure 

to follow all instructions listed below may result in 
electric shock, fire and/or serious injury.

b)  Operations such as grinding, sanding, wire brushing, 

polishing or cutting-off are not recommended to be 
performed with this power tool. 

Operations for which 

the power tool was not designed may create a hazard 
and cause personal injury.

 c)  Do not use accessories which are not specifically 

designed and recommended by the tool 
manufacturer. 

Just because the accessory can be 

attached to your power tool, it does not assure safe 
operation.

d)  The rated speed of the accessory must be at least 

equal to the maximum speed marked on the power 
tool. 

Accessories running faster than their rated 

speed can break and fly apart.

e)  The outside diameter and the thickness of your 

accessory must be within the capacity rating of your 
power tool. 

Incorrectly sized accessories cannot be 

adequately guarded or controlled.

f)  Threaded mounting of accessories must match the 

grinder spindle thread. For accessories mounted by 
flanges, the arbour hole of the accessory must fit 
the locating diameter of the flange. 

Accessories that 

do not match the mounting hardware of the power 
tool will run out of balance, vibrate excessively and may 
cause loss of control.

g)  Do not use a damaged accessory. Before each use 

inspect the accessory such as abrasive wheels for 
chips and cracks, backing pad for cracks, tear or 
excess wear, wire brush for loose or cracked wires.  
If power tool or accessory is dropped, inspect for 
damage or install an undamaged accessory. After 
inspecting and installing an accessory, position 
yourself and bystanders away from the plane of 
the rotating accessory and run the power tool at 
maximum no-load speed for one minute.

 

Damaged accessories will normally break apart during 
this test time.

h)  Wear personal protective equipment. Depending on 

application, use face shield, safety goggles or safety 
glasses. As appropriate, wear dust mask, hearing 
protectors, gloves and workshop apron capable of 
stopping small abrasive or workpiece fragments. 
The eye protection must be capable of stopping 
flying debris generated by various operations . 

The 

dust mask or respirator must be capable of filtrating 
particles generated by your operation. Prolonged 
exposure to high intensity noise may cause hearing 
loss.

i)  Keep bystanders a safe distance away from work 

area. Anyone entering the work area must wear 
personal protective equipment. 

Fragments of 

workpiece or of a broken accessory may fly away and 
cause injury beyond immediate area of operation.

j)  Hold the power tool by insulated gripping surfaces 

only, when performing an operation where the 
cutting accessory may contact hidden wiring or its 
own cord.
