Page 6: Basic Structure
BASIC STRUCTURE Basic modules The machine can be separated into three basic modules: 1. The gear housing with three gear selection positions. 2. The gear box cover which is the bearing carrier for the shafts in the gear housing and separates the oil-filled gear housing from the electric motor. - Page 7 BASIC STRUCTURE Oil change in gear housing You can change the oil when the motor has been removed from the gear housing. Turn the machine vertically with the motor facing up when dis - mantling. Oil change You must change the oil at 300 hour operational intervals. Drain and top up the oil through the hole in the motor shaft.

Page 8: Gear Housing - Primary Shaft
GEAR HOUSING – PRIMARY SHAFT Function The gear housing contains a transmission that reduces the high speed of the electric motor to a lower speed on the spindle shaft. Transmission is based on three shafts: primary shaft (A), intermediate shaft (B) and spindle shaft (C). The electric motor powers the top gear wheel on the primary shaft. -

Page 12: Gear Housing - Spindle Shaft
GEAR HOUSING – SPINDLE SHAFT Function The spindle shafts gear wheel is driven by the upper gear wheel of the inter - mediate shaft. At the upper storage point, water is supplied to the drill spindle. The transmission in this machine is rarely the cause of any problems. Incorrect handling of the machine could, however, cause the actual spindle shaft to bend, or damage the tool bracket. - Page 13 GEAR HOUSING – SPINDLE SHAFT Bearing replacement – spindle bearings Remove inner circlip When the spindle shaft has been removed from the gear housing, you can remove the bearing from the shaft. First remove the circlip. Pull the shaft out of the bearing The ball bearing is forced fitted onto the shaft.

Page 15: Carbon Brushes
CARBON BRUSHES Replacing the carbon brushes The two carbon brushes transfer electric current to the motor's rotor. The carbon brushes are wear parts that must be checked regularly. Every week if the machine is used on a daily basis. You should replace the carbon brushes when around half is left. You can easily measure this using a slide gauge without removing the brushes. -

STATOR – 230 V Functional test Fractures to the stator winding are easiest to indicate using the check below. In general, short-circuited windings can also be identified, particularly if the short circuit eliminates current in several winding turns. If the short circuit only eliminates a few turns, the measurement is unlikely to record this. -
