Gear housing/electric motor
Virtually all service work requires the separation of the gear
housing from the electric motor.
Oil change
Oil changes are made through the hole in the electric
motor's drive shaft in the gear box cover.
Separation
Motor/gear housing
1. Remove the 4 screws in the
handle
2. Part the handle and remove
one half.
3. Remove the screws next to the
spirit levels.
4. Lift out the motor.
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.
You must change the oil at 400 hour operational intervals. The oil is poured
out and topped up through the hole in the motor shaft. Volume around 0.25
litre. Oil quality: Mobil Lube 1 SHC 75W90 or equivalent quality.
Replace seals – gasket set 515 98 07-01
New seals must always be fitted in connection with an oil change.
The gasket set 515 98 07-01 contains the gasket and O-rings which must be
replaced between the motor and the gear box cover.
1. Clean the seal surfaces carefully before fitting. 2. Fitting the gasket. Apply
grease under the gasket to keep it in place when assembling (illustration 4).
3. Lubricate the O-rings and fit these. 4. To avoid damaging the seals it is
important the motor is precisely aligned with the gear housing when assemb-
ling. Press the motor together parallel to the gear housing and tighten the
screws alternately.

electric motor attached to the gear
housing.
