Cold Hammering
If the demolition hammer is stored for long periods of time
or at cold temperatures, the lubrication may become stiff
and the demolition hammer may not hammer initially or the
hammering may be weak.
Should this occur, insert an accessory into the demolition
hammer, turn the demolition hammer on and apply the end
of the accessory against a scrap piece of concrete or timber.
Turn the demolition hammer on and off every few seconds.
After 15 seconds to 2 minutes, the demolition hammer
should have started to hammer normally. The colder the
demolition hammer, the longer it may take to warm up and
function like normal.
Note:
Always wait until the accessory has stopped moving
before putting down the demolition hammer.
Operating the Demolition Hammer
For the best penetration rates in concrete, run the demolition hammer with a steady
pressure, but do not use excessive force as this will decrease the efficiency of the
demolition hammer.
Do not use the flat chisel as a “pry bar”. Using the flat chisel for prying or pushing debris
away from your work area will damage the flat chisel and potentially cause damage to your
demolition hammer. Such damage will void your warranty.

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.

• Keep the ventilation vents of the demolition hammer clean at all times.
• 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.
Gear Box Grease Replenishment
The grease in the gear box will require replenishment after approximately 50 hours
accumulative use. After this time, add approximately 30 / 50 grams (approx 2-3
teaspoons) from the supplied tub of grease into the gear box.
First remove the grease cap from the top of the demolition hammer by using screwdriver.
Once removed, add the grease through this hole. Ensure the grease cap is secured back
into position prior to operation.
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
chipping 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 tool. 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.
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.
