A grinding wheel that has been
improperly installed may crack and
disintegrate during operation resulting
in severe injury to the operator.

A damaged grinding wheel may
disintegrate during use due to high­speed operation of the unit. This can
cause wheel fragments to eject at very
high rates of speed.

Always maintain proper grinding wheel
maintenance, check for visible cracks
and perform a “ring test.” (A good
grinding wheel will sound a clear musical
tone when tapped gently with a metal tool
like an Allen wrench.) See Fig 4, page 6.

Do not force a grinding wheel onto the
machine or alter the size of the mounting
hole. Do not use a wheel that does not fit
exactly. We recommend use of Oregon

®

grinding wheels only.
Make sure the mounting-flange nut is

serviceable and not damaged in any way.
If grinding wheel vibration should occur
when the grinder is started, or running,
remove and inspect the mounting flange
and the grinding wheel.

To avoid possible grinding-wheel failure,
always allow a new grinding wheel to run
at operating speed for at least one minute
before grinding or dressing.

The hazard of kickback resulting in serious
injury to operator is increased if cutting
chain guard drive links or guard tie straps
have been reversed, removed, or filed
down. To avoid injury Do not use a cutting
chain that has been altered in any way.

Cutting chain depth gauges not properly
filed can substantially increase the risk of
kickback and injury. To reduce likelihood
of injury, always file depth gauges to
original profile.

Dressing the grinding wheel places the
fingers of the operator in close proximity
to the grinding wheel. Contact with a
rapidly turning wheel may result in injury.
Wear gloves.

Always work cautiously, maintain a strong
grip on the dressing brick, and watch
what you are doing at all times.

Do not use the side of the grinding wheel
for grinding.

All bystanders should be

kept at a safe distance from work areas.

22.. WWeeaarr pprrooppeerr aappppaarreell..

Never wear loose
clothing, neckties, bracelets, rings or any other
jewelry that could come into contact or get
caught in the grinding wheel or any other moving
parts. Non-slip footwear is recommended. Wear
protective hair covering to contain long hair.

33.. AAllwwaayyss uussee ssaaffeettyy ggllaasssseess oorr ffaaccee

Always wear gloves and protec­tive eyewear while operating the grinder and while
profiling the wheel using the dressing stone.
Also use face or dust mask if cutting operation is
dusty. Everyday eyeglasses do not have impact
resistant lenses, they are not safety glasses.

Also, make sure that the voltage and
frequency indicated on the plate applied to
the grinder correspond to those of the
power outlet.

from the outlet immediately
if the power cable/cord is damaged or cut. For
cable/cord repair or replacement, contact your
authorized dealer or service center.

NNoottee::

The
power supply cable/cord comes complete with
terminals and circuit protection. Connecting the
power supply cable/cord terminals directly into the
switch completes the electrical system for the
grinder. The final electrical connection to the outlet
should be made in such a way as to prevent
damage by individuals or passing vehicles that
could endanger both them and the operator.

Keep this manual for future reference.
To ensure the correct use of the grinder and

to prevent accidents, do not start working
without having read this manual carefully.

This manual explains how the various
components work and provides instructions
for carrying out the necessary checks and
maintenance operations.

SAFETY RULES AND PRECAUTIONS

The use of accessories or attachments not recommended by the

manufacturer may result in a risk of injury to the operators or bystanders!

INTRODUCTION

1122.. KKeeeepp wwoorrkk aarreeaa cclleeaann..

Cluttered areas and
benches invite accidents. Make sure that the working
area of the grinding wheel is free of tools or other
objects before starting up the grinder. Frequently
clean grinding dust from beneath the grinder.

1133.. DDoonn’’tt uussee iinn aa ddaannggeerroouuss eennvviirroonnmmeenntt..
Don’t use power tools in damp or wet locations,
or expose them to rain. Be sure to keep the work
area well lighted.

wheel mounting flange nut.

1188.. SSeeccuurree wwoorrkk..

Make sure that the grinder is
secured as shown in Figures 1-3, page 6. Use the
vise to hold the chain. It frees both hands for mov­ing the grind head/wheel down to grind the chain.

1199.. DDoonn’’tt oovveerrrreeaacchh..

Keep proper footing and

balance at all times.

2200.. NNeevveerr ssttaanndd oonn aann uunnssttaabbllee ppllaattffoorrmm..
Always work in a stable and safe position. Serious
injury could occur if the grinder is tipped or if the
cutting tool is unintentionally contacted.

2211.. CChheecckk ffoorr ddaammaaggeedd ppaarrttss..

Before using the
grinder, check to make sure that all the devices,
those for safety and others, are in good working
order and free from any obvious damage that could
affect performance and safety/reliability during use.

2222.. UUssee rreeccoommmmeennddeedd aacccceessssoorriieess..

Consult the
owner’s manual for recommended accessories.
The use of improper accessories may cause risk
of injury. Use only flanges furnished with the
grinder. To guarantee the efficient and consistent
operation of your grinder, remember that any
worn or broken parts must be replaced using only
original spare parts.

modified grinder. Do not remove, damage, or
disable any safety devices.

2255.. AAllwwaayyss uussee tthhee rriigghhtt ttooooll ffoorr tthhee jjoobb

use the grinder to cut or grind objects other than
saw chains. Don’t force grinder or attachment to
do a job for which it was not designed.

2266.. MMaaiinnttaaiinn ttoooollss wwiitthh ccaarree..

Keep tools sharp

Keep the cable/cord away from heat, oil,

and sharp objects.

3311.. UUssee pprrooppeerr eexxtteennssiioonn ccoorrdd..

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 you will need to
perform your grinding operation. An undersized
cord will cause a drop in line voltage resulting in
loss of power and overheating. Table 1, page 8,
shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge
number, the heavier the cord.
