C. Tamper Proofing
A tamper-proof means is in place on the following adjust-
able components prior to machine shipment. This can
either be tamper-proof paint, or a steel tamper-proof cap.
DO NOT attempt to defeat, by-pass or alter any tamper-
proof device.
• Hoist cylinder counterbalance valves (1)
• Main valve port relief valves (5)
• Extend cylinder counterbalance valves (2)
• Steering relief valve (1)
• Fork cylinder counterbalance valves (2)
• Pilot relief valve (1)
• Main system relief valve (1)
• Park brake relief (1)
D. Fork Ratings
All approved forks for this vehicle are marked with a
maximum load capacity rating. This rating is stamped on
the left edge of the fork, just below the fork pivot shaft
(Fig. 2–2). The rating is listed in U.S. pounds and based
upon a 24" (610 mm) load center.
This rating specifies the maximum load capacity that the
individual fork can safely carry at a maximum load center
of 24" (610 mm).
Since forks are always used in multiples, the total rating
of any combination of forks is the sum of their rated
capacity.
Other than block forks, use all forks in matched pairs.
Use block forks in matched sets.
Figure 2–2. The stamped fork rating specifies the
maximum load capacity that the individual fork can
safely carry at a maximum load center of 24 " (610 mm).
