Maintenance

WARNING. Always ensure that the tool is switched off and
the plug is removed from the power socket before making
any adjustments or maintenance procedures. Wear eye
protection when carrying out cleaning.
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. Some maintenance products
and solvents may damage the plastic parts; these include
products containing benzene, 25 trichloroethylene, chloride
and ammonia.
CAUTION. Water must never come into contact with the
tool.
Take special care to keep the ventilation inlets/outlets free
from obstruction; cleaning with a soft brush followed by
a compressed air jet will usually be sufficient to ensure
acceptable internal cleanliness.
If the supply cord needs replacing, the task must be carried
out by the manufacturer, the manufacturer's agent, or a
power tool repair centre in order to avoid a safety hazard.
Regularly check that all the fixing screws are tight. They
may vibrate loose over time.
Regularly check to see if any dust or foreign matter has
entered the grilles near the motor and around the trigger
switch. Use a soft brush to remove any accumulated dust.
Wear safety glasses to protect your eyes whilst cleaning.
Re-lubricate all moving parts at regular intervals.
Excessive sparking generally indicates the presence of dirt
in the motor or abnormal wear on the carbon brushes.

Replacing Carbon Brushes

Using a flat headed
screwdriver, twist the
screwdriver anti-clockwise to
undo the Carbon Brush Cap
(9) (Fig. T). Then remove the
cap.
Remove carbon brush from
the tool and replace with new
brush.
Put the carbon brush cap back onto the tool. Using a flat
head screwdriver twist the cap clockwise until tight.
When complete, repeat same steps on the opposite side.
Storage
Store the tool, instruction manual and accessories in a
secure place. In this way you will always have all the
information and parts ready to hand.
