MAINTENANCE
•
Keep the ventilation vents of the demolition hammer clean at all times, if
possible, prevent foreign matter from entering the vents.
•
After each use, blow air through the demolition hammer housing to ensure it is
free from all dust particles which may build up. Build up of dust particles may
cause the demolition hammer to overheat and fail.
•
If the enclosure of the demolition hammer requires cleaning, do not use solvents,
but a moist soft cloth only. Never let any liquid get inside the demolition hammer;
never immerse any part of the demolition hammer into a liquid.
Carbon brushes
When the carbon brushes wear out, the demolition hammer
will spark and/or stop. Discontinue use as soon as this
happens. They should be replaced prior to recommencing use
of the demolition hammer. Carbon brushes are a wearing
component of the demolition hammer, therefore not covered
under warranty. Continuing to use the demolition hammer
when the carbon brushes need to be replaced may cause
permanent damage to the demolition hammer. Carbon
brushes will wear out after many uses but when the carbon brushes need to be
replaced, take the demolition hammer to an electrician or a power tool repairer for a
quick and low cost replacement. Always replace both carbon brushes at the same time.
Gear Box Grease Replenishment
The grease in the gearbox will require replenishment after approximately 50 hours of
accumulative use. After this time, add approximately 30 / 50 grams (approx 2-3
teaspoons) from the supplied tub of grease into the gearbox.
First remove the grease cap (6) from the demolition hammer by using the hex key to
loosen all four bolts. Once removed, add the grease through this hole. Ensure the
grease cap (6) is secured back into position with all four bolts properly fastened prior
to operation.
Note:
Ozito Industries will not be responsible for any damage or injuries caused by
the repair of the demolition hammer by an unauthorised person or by mishandling of
the demolition hammer.
Re-sharpening the chiselling tools
Good results are only achieved with sharp chisels,
therefore sharpen the chiselling accessories
regularly. This prolongs the service life of the tools
and ensures good working performance.
Sharpen chiselling tools using grinding wheels (e.
g., ceramic bonded corundum wheel) with a
steady supply of water. Recommended values for
this purpose are shown below. Take care that no
annealing coloration appears on the cutting
edges, otherwise the hardness of the chiselling
tools will be impaired
