Fold up Fig. 7 1. Activate extend cylinder (marked: Red) to lift end of side sections (A) as much as possible. Fig. 8 2. Activate raise/lower cylinder (marked: White) to full length. Roller will lift from ground Fig. 9 3. Activate extend cylinder to fold side sections in. -
Page 18: Maintenance
Maintenance Good maintenance ensures long service life and optimum use. Grease nipples are fitted where wear is heaviest. Tighten all screw connections after first working day. Check all split pins and bolts to avoid mechanical failure. Check hydraulic system for leaks. Lubrication Fig. -
Page 19: Adjustment
Adjustment Wheels Lubricate and adjust wheel bearings at least once annually. Check tyre pressures at least once annually (see recommended pressure on tyre). Adjustment and lubrication of wheel bearings 1. Remove hub caps. 2. Remove split pin. 3. Tighten castle nut 1/6th of a turn until hole is aligned with axle. Turn wheel, check for resistance. -
Page 20: Replacement Andrepairs
Replacement and repairs Safety is vital for all repair work on the roller. Always observe the following points, plus those under Safety First in the instruction manual. When replacing cylinders, always fill new cylinder with oil before pressurising sys- tem. - Page 21 Activate extend cylinder after fitting until cylinder shows movement. Reverse cyl- inder until it returns to start position. Move cylinder backwards and forward sever- al times. Raise roller fully onto wheels, extend side sections fully to bleed system. Ensure no personnel are within the extension radius of the side sections. Replacing gaskets REMOVAL: 1.
