8. Maintenance and Troubleshooting

Important: Read and understand all the health and
safety information before attempting to maintain or
repair this product.
WARNING! ALWAYS ensure that the tool is
switched off, disconnected from the power
supply and that the bit has cooled before
performing any maintenance or adjustment to
this product.
Other than gearbox care, any servicing on the product
should be carried out by authorised service agents
ONLY.

8.1 General Maintenance

• Keep the tool body, chuck and bits clean and free from
dust and debris.
Clean the tool body with a damp cloth ONLY.
Important: DO NOT allow moisture to pass inside
the tool.
− Clean the chuck and dust cover with a dry cloth
ONLY to prevent dust clogging in and around the
opening.
− Clean the bits with a damp cloth and lightly
grease the shaft before inserting it into the chuck.
CAUTION! DO NOT use solvents or other
aggressive chemicals to clean the tool as it
may damage plastic or insulated parts.
• Keep all air vents and openings free from dust and
debris.
• Keep the bits sharp to reduce the workload of the tool.
• Store the tool in a clean and dry location, out of reach
of children.

8.2 Gearbox Care

This product includes a greased gearbox. The grease
should be changed at the same time that the carbon
brushes are replaced to ensure that the gearbox remains
well-lubricated. Loss of impact pressure may also
indicate that the gearbox requires re-greasing. General
lithium-based grease, such as the grease pot (E)
supplied, should be used.

1. Disconnect the power supply and ensure that the tool
is completely cool.
WARNING! The area around the gearbox and
its contents become hot during use. ALWAYS
ensure that the tool has cooled thoroughly
before maintaining the gearbox.
2. Use the two-pin spanner (D) to remove the gearbox
access cover (3) by rotating it anticlockwise.
3. Carefully wipe out the old lubricant and apply no
more than 30g of fresh lithium-based grease.
WARNING! DO NOT overpack the gearbox
with grease. Overfilling may cause the tool
to fail, overheat, or deliver reduced
performance.
4. Replace the gearbox access cover and tighten it
securely.
Important: DO NOT overtighten or apply excessive
force to the gearbox cover as this may damage the
cover thread. If the cover shows any signs of damage
or wear, DO NOT use the tool until it has been
replaced.
WARNING! DO NOT use grease aerosols with
this product.
