Every UT50, UT60 and UT70 internal combustion counterbalanced forklift truck, P variants included, is covered by this 80-page Utilev UT50P, UT60P, UT70P service manual PDF (OEM ID 76500014), so you know it matches your fleet before you buy. Wiring schematics trace the fuse box, combination switch and instrument cluster circuits, while the hydraulic system schematic maps oil from the pump through the multi-way directional valve and flow regulator to the lift and tilt cylinders. Troubleshooting tables cover the torque converter, drive axle, steering, brakes and mast, and the lifting section takes you through mast removal, adjustment and commissioning, plus Cummins and GM 4.3L engine diagnostics. On 5T to 7T trucks, set the main safety valve at 19±0.25 MPa and the steering safety valve at 9.8±0.25 MPa. One wrong relief setting can cost you a pump. The bookmarked, text-searchable PDF travels on a laptop or phone to wherever the truck sits, dock or yard.
