• Check for loose or missing bolts, worn or damaged
hoses, hydraulic leaks, and damaged or missing
fork stops.
• Inspect lower hooks for wear and proper clearance.
Adjust if necessary, refer to the Section 4.1-2,
Step 4. Tighten lower hook capscrews to 120 ft.-lbs.
(165 Nm).
• Tighten backrest capscrews (Cascade) to

• Inspect upper and lower bearings for wear. If any
bearing is worn to less than 0.09 in. (2.5 mm)

daily inspections and 1000-hour maintenance, forks
in use shall be inspected at intervals of not more than
12 months (for single shift operations) or whenever any
defect or permanent deformation is detected. Severe
applications will require more frequent inspection.
Fork inspection shall be carried out by trained
personnel to detect any damage that might impair safe
use. Any fork that is defective shall be removed from
service. Reference ANSI B56.1-2005.
Inspect for the following defects:
• Surface cracks
• Straightness of blade and shank
• Fork angle
• Difference in height of fork tips
• Positioning lock
• Wear on fork blade and shank
• Wear on fork hooks
• Legibility of marking
