Operation
Always use the auxiliary handle
(4) and firmly hold the tool by
both auxiliary handle and switch
handle during operations. Turn
the tool on and apply slight
pressure on the tool so that the
tool will not bounce around,
uncontrolled. Pressing very hard
on the tool will not increase the
efficiency.
Maintenance
•
The grease in the gearbox
will require replenishment
after approximately 50 hours
accumulated use. After this
time add approximately 30
grams of grease into the
gearbox. First remove the
gear box cover plate (3)
and washer from the tool
by removing the 4 retaining
screws using an allen key
then remove the metal cover
and washer. Add the grease
through this hole. Ensure the
washer and gear box cover
plate are put back into position
and secured with the 4 allen
key screws prior to operation.
•
After each use, blow air
through the tool housing to
ensure it is free from all dust
particles that may build up.
Build up of dust particles may
cause the tool to overheat
and fail.
•
If the enclosure of the tool requires cleaning do not use
solvents but a moist soft cloth only. Never let any liquid
get inside the tool. Never immerse any part of the tool
into a liquid.
•
When the carbon brushes wear out the tool will spark
and/or stop. The brushes are a wearing component of the
tool and should be replaced prior to the carbon wearing
out fully. Brushes will wear out after many uses but before
they do take the tool to an authorised service agent for
quick and low cost replacement. Always replace both
brushes at the same time.
Note:
909 will not be responsible for any damage or injuries
caused by the repair of the tool by an unauthorised person
or by mishandling of the tool.
Cleaning
1. Keep your machine and its cord clean. The outside of the
machine can be cleaned using a damp soft cloth with a
mild detergent if required.
2. Some maintenance products and solvents may damage
the plastic parts; these include products containing
benzene, trichloroethylene, chloride and ammonia.
3. Excessive sparking generally indicates the presence of
dirt in the motor or abnormal wear on the carbon brushes.
4. Take special care to keep the ventilation inlets/outlets free
from obstruction; cleaning with a soft brush will usually be
sufficient to ensure acceptable internal cleanliness.
5. Wear eye protection when carrying out cleaning.
CAUTION.
Do not use cleaning agents to clean the plastic
parts of the drill.
Power cord maintenance
If the supply cord needs replacing, the task must be carried
out by the manufacturer, the manufacturer's agent, or an
authorised service centre in order to avoid a safety hazard.
