6.1.2

Lubrication and assembly of wheels

•

Underlay the machine so that the wheels can freely turn. The machine must be
secured against spontaneous movement.

•

Dismount the nut and the outer cone by using the spanner No. 15. Remove the
wheel from the axis.

•

Press the bearings out of the hub in the plastic rim. Wash them from dirt and old
grease.

•

Fill the bearings inside with a new grease (e.g. for water pumps) and press them
back into the hub in the plastic rim of the wheel. Grease the inner and outer cones as
well.

•

Put the wheel back and screw the outer cone. Screw the nut and tighten the cone
against the nut so that the wheel can freely turn but does not show any greater side
clearance.

6.1.3

Maintenance of tension pulley litz wire

In order to guarantee a low operating force on the operating horizontal bar
controlling the drive of the string head, it is adviceable to lubricate the litz wire in the
Bowden at least 2x during the season with an oil available in atomiser (e.g. SILKAL,
MD Spray, WD40).

6.2

Tightening of bolted connections

Check the tightening of bolted connections. Prior to each use of the machine, check
the bolt fastening the string head to the shaft for tightness; check the tightness of bolts
fastening the string holder to the string head.

6.3

Replacement of V-belt and adjustment of tension pulley

The V-belt should be replaced according to its wear (cracked sides, torn belt, sides
worn out down to belt carrier fibres, belt pulled out of shape) or after about 100 hours of
operation at the maximum. In this machine, the belt stretched to maximum is considered
a belt in which the distance between the internal belt surfaces is lesser than 7 mm (Fig.
15 bottom) with the pressed horizontal bar of string head drive clutch.

Problem Cause Remedial

action

Tightening pulley does not stress
the belt sufficiently

Set-up tightening pulley by
means of adjustment bolt (see
Fig. 14)

Litz wire fallen out from
tightening pulley lever

Put the litz wire back

V-belt fallen behind tightening
pulley or down from belt pulley

Put the belt back

V-belt torn

Replace the belt with a new one

String head does not turn

Excessive belt extension (see Fig.
15 bottom)

Replace the belt with a new one
