Operating & Safety Guide 637

Familiarise yourself with the switches and their
location so that you can operate them quickly in

an emergency.

All that remains is to plug the Die Grinder into its

power supply and switch the supply ON.

Always position yourself so you can control the Die
Grinder while staying clear of the Grinding head.

Take extra care when you first use the grinder, as

the head will try to wander off line upon first contact
with the workpiece.

DO NOT move the grinder quickly in different
directions as the gyroscopic forces could cause you to

loose control of it and damage the workpiece, or cause
you personal injury.

Switch the unit ON and wait for the head to reach
operating. Now you can begin grinding.

Allow the head to work at its own speed, harder

materials will take longer to remove.

Keep the head moving, if you stay too long at one
place, the work will over heat.

Take your time and don’t over do it. You are more
likely to have an accident if you are tired or rushing.

Never push the equipment beyond its design
limits. If it will not do what you want with reasonable

ease and speed, assume you have the wrong tool for the
job. Contact your local HSS Hire Shop for advice.

Keep the equipment clean, you will find this less of a
chore if you clean it regularly, rather than wait until the
end of the hire period.

Use only die grinding heads supplied by HSS.

When not in use, store the equipment somewhere
clean, dry and safe from thieves.

Switch the unit OFF and wait for moving parts to
stop. Then unplug the equipment.

Clean off any powder deposits, paying special

attention to motor ventilation slots.

Then neatly coil the flex and give the tool a final
clean up ready for return, to your local HSS Hire Shop.

GENERAL SAFETY

Watch your footing. Take special care if working other
than on firm, level ground.

This tool has no guard covering the grinding head,

be aware of its position at all times.

Ensure that the grinding sparks are not directed at any
person or item which is flammable or may be damaged
by heat.

The machine is designed to be used as a grinder

and must ONLY be fitted with the appropriate grinding
heads. DO NOT use it for any other purpose.

COSHH information sheets are available from your local
HSS Hire Shop.

The HSS Die Grinder requires a 110v power supply
And must be provided with a suitable 110v
generated supply, or powered from the mains via a

suitable 110v transformer (minimum 2.2kva tool rating).

If the equipment fails, or if its power supply cable or
plug becomes damaged, return it. Never try to repair
it yourself.

Keep cables out of harm’s way, and clear of the
work area.

Extension leads should be fully unwound and
loosely coiled, away from the equipment. Never run

them through water, over sharp edges or where they
could trip someone.

Using electrical equipment in very damp or wet
conditions can be dangerous.

To reduce the risk of electric shock, use a
suitable RCD (Residual Current-Operated Device)

available from your local HSS Hire.

Ensure the Die Grinder and power socket are switched
OFF before plugging into the power supply.

If a grinding head is not fitted or a replacement is
required, unplug the machine from its power supply.

Insert the shaft lock pin into the spindle hole so that

it lines up with the two stirrups on the front body casting.

Turn the chuck lock bolt anti-clockwise with the
spanner provided and if required, remove the old
grinding head. Insert the new head fully in, then lock

in position by turning the chuck lock bolt clockwise.

Remember to remove the pin and spanner
before proceeding.

To switch the Die Grinder ON push the ON/OFF
thumb switch forward until it clicks in position. To
switch it OFF, press the rear of the switch and it will

spring back to the OFF position.
