... have you been trained

The law  requires that personnel using this type of equipment in

the workplace must be competent and qualified to do so.

Training is available at HSS Training 

0845 766 7799

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 equipment for the job. Contact
HSS Hire 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.

When not in use, store the equipment somewhere in a
heated, dry area. Otherwise they may be damaged by
condensation and cold.

EQUIPMENT CARE

FINISHING OFF

Switch off floor grinder by turning the switch to

“0” position and holding it for 1-2 seconds.  

Switch off dust extractor. Remove the waste bag and
lower the machine down. 
Clean both machines.
Neatly coil flexes 

ready for return to HSS Hire.

BASIC TECHNIQUES

Having prepared the grinder, 

wheel the machine to the

far corner of the floor, placing it as close to the corner as
possible. 
Connect the machine to power supply. Make sure the
emergency button is reset. Turn the power switch to “I”

in order to start the grinder. 

Hold the knob in start

position for 1 - 2 seconds. 
Do not hold the knob in “I” position for longer than is
needed to start the machine. Holding the switch in start
position “I” for longer will damage the machine. 
During the operation push the machine forward over
the floor surface.  

When work is done turn the power off by turning the
switch to “0” position and unplug from mains.

EMERGENCY STOP SWITCH

When the emergency stop switch is pressed, all
electrically-powered equipment of the machine is
switched off. 
Do not use the emergency stop switch to stop the
machine, except in emergency. 
As long as emergency button is pressed the machine
cannot be started. Reset by turning the switch 45

o

clockwise so it pops out again.

The machine then can be

restarted. 

EDGE GRINDER

The edge grinder provides increased flexibility in the
use of the machine. With edge grinder it is possible to
grind edges and corners effectively from different
directions.    

WORKING WITH DUST EXTRACTOR

Prepare the dust extractor by fitting a waste bag. Place
the dust extractor where you want to start the
vacuuming work. Connect the dust extractor to mains
supply. Start the dust extractor putting the switch into
the position  “I”.

In order to keep the suction hose for the dust extractor
and the power cable out of the working area and/or path
of  the  machine  the   hose  and  the   cable  can  be

LIFTING AND TRANSPORTATION

Always transport the machines in upright position. The
grinder should also have the handle in upright position.
The dust extractor however, must be lowered. 

Make sure

they are anchored securely to  surrounding

to prevent

them from moving. The securing straps or other equipment
used for anchoring during transport must be tightened
over non-moving parts, e.g. the dust extractor's chassis.

The grinders may only be lifted using the lifting eye on
the chassis in accordance with the relevant instructions.
The lifting handles on the motor are intended for lifting
the grinding head, when it is separated from the
chassis, and then only for short, low lifts, 

e.g. into the

boot of a car.

The lifting handles are not to be used for

lifting the complete machine.

When lifting the dust extractor, 

use

lifting straps that must be fastened in
the notches on the chassis. Only use
straps approved for lifting equipment.
Do not transport the dust extractor on
sloping surfaces, e.g. loading ramps,
without securing it properly, for
example with a winch.

This is a safety

measure in case the dust extractor starts
to roll out of control. 

Also make sure

that people

(including the operator) 

in

the vicinity are at a safe distance in
order to prevent personal injury, in
the   event   that   the   dust   extractor

WARNING!

If the catches are not properly located in the lugs,

there is a risk that the dust cylinder package can

drop, with a consequential risk of crash injury

arranged. 
By arranging the hose
and cable as shown you
avoid disruptive
stoppages caused by
having to reposition the
cable and hose.

LOWERING DUST EXTRACTOR

When the dust extractor is in the operation position and
you want ot lower it to transport or parking position, first of
all

lift the dust cylinder with both hands

using the lift handles. To avoid the risk of
the suction system tipping, place foot on
the collection plate for the waste bag. 
Lift the dust cylinder package up and out a
little, so the catches release. Then let the
dust cylinder package drop slightly and
fold in the dust cylinder package again, so
the catches fasten in the lower lug on the
chassis for transport position. 

WARNING!

There is a risk of crush injuries while lowering to the

transport or parking position. Use the lifting handles

to avoid trapping your hands and fingers. 

WARNING!

During grinding, the tools become very hot. Tip the

machine back and allow it to stand for a short while. 

CAUTION!

Some parts of the machine can become very hot

during work. There is a risk of burning your hands. 

WEAR PROTECTIVE GLOVES

starts to roll out of control.

When the dust extractor is to be hoisted, 

it must be

securely anchored in the notches for secure lifting

,

which  are  found  on  both  of  the  chassis'  long  sides.  

To

prevent the dust extractor from tipping, make sure to
pull with equal force so the dust extractor doesn't twist
and end up on its side.

The swivelling wheel must be pointing forwards in the
direction of travel.
