Handle attachment (Fig.4)
For safety reasons, only use the hammer drill with handle attachment.
You will be able to achieve a safe body position during operation by rotating the handle
attachment.
Loosen and turn the handle attachment in an counterclockwise direction. Then tighten the
handle attachment.
Depth stop (Fig.5)
Loosen the handle attachment and place the straight part of the depth stop into the hole.
Adjust the depth stop and re-tighten the handle attachment.
Dust collection device (Fig. 6)
Before doing any overhead hammer-drilling work, attach the dust-collecting cup over the drill bit.
Drill Stop (Fig.8)
• You can deactivate the drilling action of the hammer drill when using it for chiseling work.
• Turn the lever selector (7) so that the mark “ TT ” coincides with the arrow (a) on the
machine case.
• To reactivate the drilling action, the lever selector (8) has to be reset so that the mark (b)
“ II TT ” coincides with the arrow (a).
Important! Too much pressure will place unnecessary load on the motor. Check the drill bits
regularly. Re-sharpen or replace blunt drill bits.
MAINTENANCE
• The grease in the gearbox will require replenishment after approximately 50 hours
accumulative use. After this time add approximately 50 grams of the grease (supplied),
into the gearbox. First remove the cap from the tool by using the pin spanner (supplied).
Once removed add the grease through this hole. Ensure the cap is secured back into
position 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 housing 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. Always replace both brushes at the same time.
Note: Northern Industries will not be responsible for any damage or injuries caused by the
repair of the tool by an unauthorized person or by mishandling of the tool.
