TRUCK LUBRICATION AND CHAIN MAINTENANCE Measuring Chain Stretch If the chains stretch beyond the recommended amount, they should be replaced in pairs. Chain stretch can be measured with a chain wear scale. See Figure 6-10. The scale indicates whether the distance between two chain links is within tolerance.
TRUCK LUBRICATION AND CHAIN MAINTENANCE 2. Check to see that an unloaded mast will completely CAUTION lift to full lift height (the relief valve opens). If it will not, check the hydraulic oil level in the reservoir and NEVER exceed 4.0° rear tilt for masts. Rear tilt in add oil if necessary.
WARNING Figure 6-12 Adjusting Tilt Cylinder. • Only trained and experienced technicians or your Landoll service representative must be allowed to service the mast assembly. Never Removing the Tilt Cylinders place any part of one’s body into the working area of the mast.
