G3 - LIFT TRUCK
TOW
The lift truck can be towed through a rigid bar hooked to the frame ears, front or rear and for short distance with slow speed.
- Block all four wheels to prevent accidental movement of the lift truck
- Shut down engine
- Put the forward/reverse lever in neutral position
- Release the parking brake
- Put the emergency lights
- put the gear selector in neutral position:
a) Disconnect and close the hydraulic “X” (Fig.G3/1) of the cylinder of the
gear selector.
b) Put the rod “Y” (Fig.G3/1) in neutral position (this is on half stroke
between two “détente”)
c) Deactivate the negative brake (fig.G3/2):
- unscrew the caps “4” and “5”
- take off the spring “7”
- with a key of 19 mm and external diameter not higher than 26 mm,
unscrew the counter nut “9”,unscrew the nut “1” untill at the position
“8”
The brake is deactivated.
Note: If the engine is not running there will be no steering or braking assistance.
Operate the steering and pedal slowly avoiding sudden jerky movements.
Reactivating negative brake
Brake cylinder regulation (fig.G3/2)
- unscrew the caps “4” and “5”
- take off the spring “7”
- with a key of 19 mm and external diameter not higher than 26 mm, screw the nut “1” till the piston is at a maximum depht of
29-29,5 mm (dimension “A”). The nut is “1” has a pitch of 1,75 mm so it’s possible to calculate how screw the nut, for exam-
ple: if the dimension “A” is of 26 mm it’s necessary to screw it of 2 turns (3,5 mm).
Check again the mesure as described and, if not right again, repeat the operations till now described.
- screw the counter nut “9” untill the nut “1”.
- mount again the spring “7” and the caps “4” and “5”.
Note: exceeding the mesure of 29,5 mm the complete unlock of the brake it’s not possible, so the brake could overheat and
damage it self quickly.
A bad regulation could cause big damages to the brakes and also a quickly destruction.
If the nut “1” is unscrewed too far the machine doesn’t brake! Dangerous to your life!
Pay attention to the dimension “B” : if it’s lower than 21,5 mm you must change the brake disk.
