Mounting the Arbor Bearing and Guard
The cutting blade drive (bearing with arbor and blade
guard) must be assembled before the machine is used for
the first time. The arbor bearing can be mounted to the
inboard or outboard side of the cast arm to suit cutting
requirements. Under normal circumstances the drive
should be mounted inboard of the arm because of the
better balance and only mounted outboard when required.
Inboard mounting
First fit V-belt (1) on the belt pulley (2) and position the
bearing plate (3) against the inside of the cast arm (4) so
that the tapped holes line up with the slots in the cast arm.
Position V-belt guard (5) against the outside of the arm
(4). Insert a hex. head screw (6) through one of the two
front holes and screw it into the bearing plate-move V-belt
guard to and fro to ease insertion. Now let go of the
bearing. Fit the other two screws (6) through the holes in
the V-belt guard (5) and screw them into the bearing plate
- the eccentric adjuster (7) must be fitted on the rear
screw.
Outboard mounting
Position the bearing plate (3) against the outside of the
arm (4) and fit the V-belt (1) on the belt pulley (2). If the
V-belt is new, this operation is easier if the M 10 hex. head
nut (8) is turned counterclockwise with the combination
wrench (17 mm), i.e. this turns the belt pulley (2). Position
bearing plate (3) so that the tapped holes line up with the
slots in the arm.
