General Information and Specifications
2.5.12 Tamper Proofing
A tamper-proof means is in place on the following
adjustable components prior to machine shipment. This
can either be tamper-proof paint, or a steel tamper-proof
cap. DO NOT attempt to defeat, bypass or alter any
tamper-proof device.
• Main Valve Port Relief Valves (4)
• Steering Relief Valve (1)
• Attachment Tilt Cylinder Counterbalance Valve (1)
• Lift/Lower Cylinder Counterbalance Valves (2)
• Extend/Retract Cylinder Counterbalance Valve (1)
• Main System Relief Valve (1)

2.5.13 Fork Ratings
All approved forks for this vehicle are marked with a
maximum load capacity rating. This rating (Fig. 2 -7, 1) is
stamped on the left edge of the fork, just below the fork
pivot shaft. The rating is listed in U.S. pounds and based
upon a 24" (610 mm) load center (2).
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
capacities. Other than block forks, use all forks in
matched pairs. Use block forks in matched sets.

WARNING:
DO NOT exceed the total
rated capacity of the specific pair of forks being
used. Forks can break causing loss of load and
possible death or serious personal injury to the
operator or personnel in the area. If the total
rated capacity of the forks exceeds the capac-
ity of the vehicle, the vehicle capacity should
not be exceeded.
