Overload Protection
To protect the user, motor and drill bit, the PLD 182.1 NT is equipped with a
mechanical and electrical overload protection.
Mechanical:
In the event of a sudden jamming of the drill bit, the
machine's kickback is limited to a reaction torque
controllable by the operator by means of a slip clutch.
Electrical:
To warn the user against overstressing the tool by applying
to high an advance force, the handle includes a LED as an
overload indicator. It does not light during idle run or at
normal load. At overload, it lights red. In that case the tool
most be stress-relieved. In case of longer non-observation
of the rad indication, the electronics will independently
switch the tool off. After relieving be switching the tool off
and on, the work can be continued as normal.
The safety clutch should absorb shock and excessive stress. It is an aid
and not an absolute protection. Therefore, you have to handle and drill
carefully. To keep it in good condition, the clutch should slip for a very
short time (max. 2 seconds) in each case only. Slipping for longer
periods destroys the safety clutch. After excessive wearing the clutch
has to be renewed by an authorized service shop.
Care and Maintenance
Before the beginning of the maintenance- or repair works
you have to disconnect plug from the mains.
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair, the unit has to be checked by an electrical
specialist. According to its design, the tool requires a minimum of care and
maintenance. However, the following maintenance works and component
checks have to be performed in regular intervals:
Clean the tool after completion of your work. Apply some grease
onto the drilling spindle thread. The ventilation slots must always be
clean and unclogged. Make sure that now water gets into the tool
during cleaning.
After the first 150 hours of operation, the gearing oil must be
changed.
Gearing oil changes bring about an essential increase of the tool's
lifetime.
After approx. 250 hours of operation, the carbon brushes must be
checked and, if necessary, be replaced by an authorized specialist
(use only original carbon brushes).
