USER MANUAL 9
drill internal components.
5) electric hand drill moves should hold the drill handle, can’t
use cable electric led or hand cable cable from the socket.
6) Transmission of rolling bearing and gear grease always keep
clean and plentiful.
7) Long-term used electric drill, application before use 500V
megohmmeter measureing insulation, resistance
between metal shell and winding, the resistance value should
be greater than 2 MQ, otherwise must be inspection on winding
and dry processing.
8) Torque control methods: screw torque adjustment ring up, is
the larger the scale value, the greater the torque. On the other
hand, the torsion n-tuning loop downward spiral, the scale value
is smaller, the smaller force.
9) Note: With a electric drill screw must want to press switch
system, its correct position is with your index nger pressure
switch system and unavailable means more pressure.
10) To avoid dust and iron lings from ventilation holes into the
drill the rotor part, don’t pull the power cord, so as not to break,
Do not use electric drill when use hammer percussion, not to
impose the impact of the radial drill shaft part.
11) Electric drill due to ventilation, cooling the long-term use
of internal dust, dust will make gear and bearing lubricating oil
mixed with metamorphic blot aggravate wear, particularly, alter-
native use. In order to guarantee the selection of the electric drill
precision, reduce because of the bearing wear and produce too
much clearance, so need to clean the fatliquoring and internal
lubrication.
