  • Page 18 ACHINE EIGHTS Before transporting or lifting the MB20N/26 machine be aware of its weight. It is very important to realise that the centre of gravity of the stowed machine is approximately 80 cm above ground and in the plane of the energy chain which is located on the back of the mast.
  • Page 19 2. Operation & Specifications 1. Never approach the MB20 from the front or rear while fork lifting. 2. Use maximum forklift tilt as soon as possible when raising the MB20/26. 3. If travelling over sloped or uneven ground it is strongly recommended to temporarily tie the MB20 jib mount structure to the forklift mast as a safety precaution.
  • Page 20 When the MB20n/26 is on the truck or trailer it should then be made secure by:- 1. Chocking the wheels.
  • Page 21 2. Operation & Specifications Proceed as follows:- (Refer to the valve block drawing Figure 6.) 1. Fully lower the jib boom and the mast sections. Rotate the mast into the stowed position. 2. Turn the Upper Control Box to the OFF position and remove the key. 3.

  • Page 27 DO NOT undertake any mechanical, electrical or structural modifications to the design of this machine. Any departure from the normal use of the machine must be certified in writing from UpRight Powered Access Ltd. or other responsible authority. Failure to abide by this instruction is a Safety Violation and a Warranty Violation.
  • Page 28 Maintenance The MB machine should be maintained while on level ground only. This will ensure that the mast rotating mechanism and the running gear are stable. The greatest risk to safety when maintaining the work platform is the sudden motion under gravity when a hose connection or built-in valve is loosened.

  • Page 37 Maintenance AILS The cage rails are fixed in position by means of 8 No. M8 ISO grade 8.8 bolts. Regularly inspect these bolts for damage and replace as necessary. The bolts should be tightened to a torque of 20.0 Nm. The cage rails are manufactured from painted aluminium alloy.
  • Page 38 Maintenance Figure 3-12: Jib Pin Removal Inspect the cylinder boss and the jib ends for bushing wear and replace as necessary. When replacing the bushings it is important to first remove burrs and lightly oil the steel bosses. Use a small mallet and drift to fit the bearings. Take care not to score the ptfe/bronze coatings as this will greatly reduce the useful life of the bearing.

  • Page 44 Maintenance If the differential dimension is greater than 6mm. then it is neccessary to tighten the loose adjuster. Return the masts to the fully lowered position and check the overall height of the mast assembly from the ground. Check that the nominal dimension is 1995 mm. If this dimension has been exceeded during chain balancing, then it is likely that one of the chain pairs the chains has been overtightened, causing the masts to rise above the normal position.
