MAINTENANCE
82
CAUTION
Check all wheel nuts after 2 to 5 hours of operation:
when new lift trucks begin operation and on all lift
trucks when the drive wheels have been removed and
installed. Tighten the nuts in a cross pattern to the
correct torque value shown in the MAINTENANCE
SCHEDULE. When the nuts stay tight for eight hours,
the interval for checking the torque can be extended
to 350 hours.
Forks
The identification of a fork is how the fork is connected to
the carriage. The
H70--110XL
series of lift trucks normally
have a hook fork. A pin fork is available for this series of
lift trucks as an option. The
H135--155XL
series of lift
trucks normally have a pin fork.
Forks, Adjustment
Hook forks
are connected to the carriage by hooks and
lock pins. The lock pins can be one of two types. See
FIGURE 18. These lock pins are installed through the top
fork hooks and fit into slots in the top carriage bar. Adjust
the forks as far apart as possible for maximum support of
the load. Hook forks will slide along the carriage bars to
adjust for the load to be carried. Raise the lock pin in each
fork to slide the fork on the carriage bar. Make sure the
lock pin is engaged in the carriage bar to lock the fork in
position after the width adjustment is made.
