To clean the product
CAUTION: Make sure that no water goes
into the motor or the gearbox.
CAUTION: Do not use running water to
clean the product.
• Use a dry or moist cloth to clean the product.
• Remove blockage from all air openings. A blocked
air intake decreases the performance of the product
and can cause the motor to become too hot.
• Clean and lubricate the spindle shaft thread.
To do maintenance of the diamond drill
bit
• Make sure that the diamond tools segments are
sharp. Sharpen blunt diamond segments with a SiC
grind stone.
• Make sure that there is no vibration in the drill bit. If
there is vibration in the drill bit, the diamond
segments can come loose.
• Make sure that the diamond segments are
sufficiently larger than the inner and outer diameter
of the drill bit tube.
• Lubricate the drill bit thread with water resistant
grease. This makes it easy to loosen the tool.
• Make sure that the radial run out at the diamond
segments of the drill bit is not more than 1 mm.
To replace the gear oil
CAUTION: If there is gear oil leakage, stop
the product and speak to an approved
service center. The gear becomes damaged
if the gear oil level is not sufficient.
• Let an approved Husqvarna service center replace
the gear oil.
To examine the water connection
CAUTION: If there is a leakage of water
from the water connection ring, the shaft
seals must be replaced immediately.
• Let an approved Husqvarna service center repair the
water connection.
