For advice on the safety and suitability of this
equipment contact your local HSS Hire Shop.

Keep children, animals and bystanders away from
the work area.

Never use this equipment if you are ill, feeling
tired, or under the influence of alcohol or drugs.

This equipment should only be used by a
competent person who has read and understood
these instructions.

Safety Goggles MUST be worn by everyone in

the work area.

Wear practical, protective clothing, gloves and
footwear.

Avoid loose garments and jewellery that

could catch in moving parts, tie back long hair.

Always switch OFF and unplug the equipment
when not in use.

Make sure you know how to switch this machine
OFF before you switch it ON, 

in case you get into

difficulty.

Always unplug the tool before making adjustments
to it. 

Check that it is switched OFF and that you have

removed the chuck key before plugging it back in. 

Having switched OFF, 

always wait for the drive head

to come to rest before putting the tool down. 

Check the condition of the equipment before use.

If it shows signs of damage or excessive wear, return it to
your local HSS Hire Shop.

Only change the direction of rotation when the machine
is stopped.

Take special care when fixing into walls or floors,
they may contain hidden pipework or electrical
cables.

If in doubt, hire a metal locator, to determine the

exact position of such hazards.

Watch your footing. 

Take special care if working other

than on firm, level ground. 

Above ground-level,

always work from a stable, purpose-made work
platform

such as a step-up or trestle.

Most HSS screwdrivers plug into a standard 13amp
power socket. 

However, 

110V models

(with a round

yellow plug) 

must be provided with a suitable 110V

generated supply, 

or powered from the mains via a

suitable 110V transformer. 

If the equipment fails, or if its flex or plug gets
damaged, return it. 

Never try to repair it yourself.

Keep flexes out of harm’s way,

and clear of 

moving parts. 

ELECTRICAL SAFETY

GENERAL SAFETY

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.

Keep the equipment dry, 

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 Shop, or power the
equipment from a mains circuit with a built-in RCD.

Never carry or pull the equipment by its flex.

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

Fit the machine with right bit for the job.

Remove the outer sleeve

to reveal the 1/4” hexagon

drive socket. 

Insert the required drive bit 

(see chart),

then replace the outer sleeve.

Plug the machine in to its power supply and 
switch ON.

Hold the tool in both hands and adopt a stable
stance that gives a good view of the work

while

keeping you clear of the bit.

Do not work in areas where you are forced to
stand on loose debris or on a slippery uneven
surface.

If possible, 

drape the tool’s flex over one shoulder to

keep it clear of the screw/fixing, 

but 

make sure

there is still enough slack

so you are not restricted in

movement.

Practice on an area of the work which will not 
be noticed.

BASIC TECHNIQUES

GETTING STARTED

Screw-driving...

All models work on the principle that, when the screw
has been driven into the material to the required depth,
the driving tip disengages from the screw. This is
achieved by adjusting the depth gauge setting. 

Fit the screw to the drive bit

(the socket is magnetic

and should hold the screw with ease). 

Set the torque

adjustment collar 

to No. 18. Confirm that the

Forward Reverse selector is set to forward.

Offer the machine up to the work,

then 

gently

squeeze the

ON/OFF 

trigger to start the bit

rotating, place enough pressure

on the machine 

to

allow the bit to stay in contact with the screw
head 

as it enters the work.

The machine will drive the screw until the depth
setting is reached, 

whereupon the bit will cease to

travel forward. 

Check the setting

of the screw and 

if

the head is imbedded too far

into the work 

or is

sitting proud of the work, adjust the depth setting.

To adjust the depth turn the 

depth 

gauge

clockwise to decrease 

the setting 

and anti-clockwise

to increase.

Once set, you should not have to make any more
adjustments, other then when the bit becomes worn.

TEK Driving...

This system of driving a hexagonal headed fixing,
requires the driving bit to stay in contact with the fixing
at all times. Therefore, you must first adjust the depth
