MAINTENANCE AND SERVICE
- Every 250 hours of work check condition of carbon brushes. If their length is
less than 5 mm they should be replaced with new genuine brushes. After replacement,
new brushes should be run-in without load for about 20 min. Repair and service work
is to be performed by authorized service agents only.
- Keep the magnet clean and free of chips, oil or other contaminants.
- Inspect arbor, sleeve and support bracket for visible wear.
- Replace any worn parts and tighten any fasteners that may have come loose during
daily usage.
CANCELLING CLEARANCE
The drive and the slider can be slid up and down smoothly using the lever (1), the screws (2) fixing
the strip to the drill body visible through the openings in the slider (5). To loosen screws (2), the
slider should be placed in such a position (using feed handles) so that the openings make the
screws visible. After loosening the screws slide the slider up and down several times so that the
pressure strip aligns itself and cancels clearance.
After carrying out these steps and canceling clearance, tighten screws (2) starting from the middle
screw. The slider should be located symmetrically relative to the middle screw. Next, tighten the
neighboring screws (2) moving the slider in the degree necessary for making them visible.
Then, tighten screws (3) until any noticeable resistance is felt. When the screw in this position and
blocked with a hexagonal key, tighten counter nut (4). The screws (3) counteract the machining
force and protect the pressure strip from shifting during operation.
