Maintenance

Replacing Carbon Brushes
Using a flat head screwdriver
open the carbon brush cap at the
opening of the carbon brushes
(14) (Fig. T).
Twist the screwdriver anti-
clockwise and remove 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.
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.
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.
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.
Excessive sparking generally indicates the presence of dirt
in the motor or abnormal wear on the carbon brushes.

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.
Wear eye protection when carrying out cleaning.
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.
T
Regularly check to see if any dust or foreign matter has
entered the grills 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.
