Get a suitable length of wire rope at least 16mm diameter, preferably with eyes / loops at each end. Feed the rope from the rear left hand side under the counter weight, under the chassis. Lift the forks slightly and slide both together slightly left of centre on the carriage. Attached the end of the rope to the 2 forks close to the heels, shackles and heavy chain may be required. Lower forks and remove slack from wire rope. Pull the rope around the counterweight towards the right side of machine, take rope outside and anchor to the heaviest thing you have, like a truck, large tractor. Start forklift operate lift whilst standing to the left of the mast tension in rope should drag the rear of the forklift around towards the doorway. Be prepared to throw away the wire rope as it will be damaged by the pull round the counterweight. Make sure rope is clear of any pipework around the front axle. You may need to do the lift operation a few times to get the forklift to the right position.
