come with practice and experience.
Forward and reverse speed control is achieved by rotating
the H-bar in the corresponding rotation.
It is important that the H-bar rotate freely. If it does not, it
may need to be cleaned or adjusted.
To adjust: Loosen the lock nuts clamping the end
bushings (Fig. 5-6). They may have been overtightened.
Loosen in 1/4 turn increments and test for ease of operation
each time. This system must be loose enough that the
springs on the pump levers will return the pumps to neutral
from the reverse position. The spring does not affect the
forward rotation, only the reverse rotation.
NOTE: The lock nuts must not be loosened too much as
this gives the operator presence control levers too much
play. These control levers must be able to move freely yet
they should not have so much play that the operator presence
control levers hang up on the handle grips. Extra washers
may be added, as required, to keep the operator presence
control levers centered. Fig. 5-6
Steering bar spring
The steering bar spring (Fig. 5-7) allows the H-bar lever to
return to the straight ahead position whenever it is released.
If it does not then the two shoulder bolts will need to be re-
adjusted.
Make certain the two shoulder bolts are touching the
lower spring when steering is in the neutral locked position.
Both shoulder bolts should barely touch the spring. If they
are not, loosen them and adjust them until they make contact
with the spring. Re-tighten the shoulder bolts. Fig. 5-8
If this does not alleviate the problem then the bushings
inside the H-bar tube may be binding. (Fig. 5-8) Inspect
them and if necessary replace or clean them to allow the bar
to move freely.
H-bar handle height adjustment
The H-bar handle can be raised or lowered. There are two
different positions that it can be adjusted to for more
comfortable operation. To make the adjustment use the
following procedure:
1. Park the unit on a level surface and turn the engine off.
