Driving And Direction Changes
The S70--120XL lift trucks have a single--speed powershift
transmission. The S135--155XL lift trucks can have either a
three--speed manual transmission and oil clutch or a two--
speed powershift transmission. The following paragraphs
describe how to operate the transmissions.
MANUAL TRANSMISSION
When the lift truck has a manual transmission, it will also
have a clutch pedal and two control levers. One control
lever is for direction control and the other control lever is for
the speed range.
To move the lift truck, release the parking brake. Depress
the clutch pedal and select the first or second gear (first
gear if the load is heavy or the lift truck is on a grade). Se-
lect the FORWARD or REVERSE direction as required.
Slowly release the clutch pedal while the engine speed is
increased with the accelerator pedal. When the lift truck is
moving easily, depress the clutch pedal and select the next
higher gear. Again release the clutch pedal while slowly in-
creasing the engine speed.
If the lift truck begins to slow down because of the load or a
grade, select a lower gear. (Do not select first gear when
the lift truck is moving.) When second gear is selected from
third gear, increase the engine speed before changing to
the lower gear. Also change to a lower gear before traveling
down a steep grade.
To change directions, apply the brakes and depress the
clutch pedal to stop the lift truck. Move the direction control
lever to select the opposite direction. Select the first or sec-
ond gear as necessary. Select a higher gear as necessary
when traveling.
CAUTION
Stop the lift truck to change the direction of travel.
Stop the lift truck before selecting first gear. The trans-
mission can be damaged if first gear is selected while
the lift truck is moving.

direction control lever. If the lift truck has a MONOTROL
pedal, push on the left side of the pedal to go FORWARD or
