8 Care and maintenance

CAUTION

Disconnect the mains plug from the power outlet.

8.1 Care of the power tool

DANGER

Under extreme conditions, when used for working on

metal, conductive dust may accumulate inside the tool.

This may have an adverse effect on the tool’s protective

insulation. Under such conditions, the tool should be

plugged into a ground fault circuit interrupter (RCD)

and use of a stationary dust removal system and

frequent cleaning of the tool’s cooling air slots is

recommended.

The outer casing of the power tool is made from impact-

resistant plastic. Sections of the grip are made from a

synthetic rubber material.

Never operate the power tool when the air vents are

blocked. Regularly clean the power tool’s air vents care-

fully with a dry brush. Do not permit foreign objects to

enter the interior of the tool. The motor’s fan will draw

dust into the casing and an excessive accumulation of

conductive dust (e.g. metal, carbon fiber) may cause

electrical hazards. Clean the outside of the power tool at

regular intervals with a slightly damp cloth. Do not use

a spray, steam pressure cleaning equipment or running

water for cleaning. This may negatively affect the elec-

trical safety of the tool. Always keep the grip surfaces

of the tool free from oil and grease. Do not use cleaning

agents which contain silicone.

NOTE

Frequent work on conductive materials (e.g. metal, car-

bon fiber) may make shorter maintenance intervals ne-

cessary. Take your individual work place risk assessment

into account.

8.2 Maintenance

WARNING

Do not operate the power tool if parts are damaged,

if the electronic control unit is defective or when the

controls do not function faultlessly. Have the power

tool repaired by Hilti Service.

WARNING

Repairs to the electrical section of the power tool may

be carried out only by trained electrical specialists.

Check all external parts of the power tool for damage

at regular intervals and check that all controls operate

faultlessly.

8.3 Checking the power tool after care and

maintenance

After carrying out care and maintenance work on the

power tool, check that all protective and safety devices

are fitted and that they function faultlessly.

9 Troubleshooting

Fault Possible cause Remedy

The power tool doesn’t start. Interruption in the electric supply. Plug in another electric appliance and

check whether it works.

The supply cord or plug is defective. Have it checked by a trained electrical

specialist and replaced if necessary.

The carbon brushes are worn. Have it checked by a trained electrical

specialist and replaced if necessary.

tivated after an interruption in the

electric supply.

Switch the power tool off and on

again.

The power tool doesn’t achieve

full power.

The extension cord’s conductor cross

section is inadequate.

Use an extension cord with an ad-

equate conductor cross section.

Malfunction in the ATC system. If necessary, the power tool should be

repaired by Hilti Service.
