Hydraulic Control Quadrant
(See Fig. 81)
The hydraulic control levers are held in
position by spring-loaded friction washers,
which, after considerable usage, may be-
come worn and allow the levers to "creep"
from their desired setting. To compensate
for wear, tighten the machine screw on each
lever, which secures the friction washer un-
til the desired tension is obtained.

Throttle Control Lever (Diesel Model)
(See Fig. 82)
The throttle control lever is fitted with
a spring-loaded friction disc, which holds
the throttle lever at the desired setting.
After considerable usage, the disc may be-
come worn, allowing the throttle control
lever to ''creep'' . To com pens ate for wear,
loosen the clamp nut beneath the instrument
panel and slide the clamp along on the throt-
tle shaft, compressing the tension spring,
until the desired lever tension is obtained.
Securely tighten clamp nut.
