Care And Maintenance; Tools And Accessories - Hilti WSJ 750-ET Operating Instructions Manual

7. Care and maintenance

Unplug the supply cord from the electric socket.
7.1 Care of blades
Used saw blades should be cleaned to remove resin
en G
deposits at regular intervals as clean blades achieve
a higher cutting performance. Resin deposits can be
removed by placing the saw blades in a bath of paraf-
fin (kerosene) or commercially available resin remover
for 24 hours.
7.2 Care of the tool
The tool was lubricated adequately when it was man-
G
ufactured. After long periods of heavy use it is rec-
ommended that the tool is inspected and serviced at
a Hilti workshop. This will increase the life expectan-
cy of the tool and avoid unnecessary repair costs.
Repairs to the electrical section of the tool may be car-
G
ried out only by a trained electrical specialist.
CAUTION
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.

WSJ-DRS
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 ventilation slots
are blocked. Clean the ventilation slots carefully using a
dry brush. Do not permit foreign objects to enter the inte-
rior of the power tool. 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 power tool.
7.3 Maintenance
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool if parts are damaged or when the
controls do not function faultlessly. If necessary, your
electric tool should be repaired at a Hilti repair center.
Repairs to the electrical section of the tool may be car-
ried out only by trained electrical specialists.
7.4 Checks after care and maintenance
After care and maintenance, check that all protective
devices are fitted and that they function faultlessly.

8.1.3 General safety precautions
