CHECKING THE HYDRAULIC CONTROL
LEVER PERFORMANCE

The hydraulic control lever guides (1) and (2) have
been shipped temporarily assembled. It is necessary
to readjust the lever guides (1) and (2).
1. Preparation before checking
(1) Start the engine.
(2) Set the throttle lever to the engine max. speed.
(3) Place the hydraulic control lever in the "DOWN"
(A) position to lower the three-point hitch.
2. Check points
(1) Place the lever in the "UP" (D) position and make
sure that the three-point hitch rises quickly.
(Shorter than 1 second for the full stroke.)
(2) Place the lever in the "DOWN" (A) position to
lower the three-point hitch.
(3) Place the lever in the "SLOW UP" (C) position and
make sure that the three-point hitch rises slowly.
(5 to 30 second for the full stroke.)
(4) Place the lever in the "SLOW DOWN" (B) position
and make sure that the three-point hitch lowers
slowly when attaching the rear implement later.
3. If any of the above check points are not satisfactory,
loosen the bolt (3) and reposition the lever guide (1) or
(2). Finally tighten the bolt (3).
If the lever does not return to the "NEUTRAL" (N)
position from the "UP" (D) position automatically,
loosen the bolt (4) and reposition the lever as shown in
