Instructions for using the restrain belt Before starting the industrial truck, pull the belt smoothly out from the retractor, pull it tight to the body over the thighs and latch it with the buckle. The belt must not be twisted when put When operating the industrial truck (e.
Automatic/Mechanical Support System (optional) Never use the truck without functional support system. Have the support system checked after each accident by authorised specialist per- sonnel. Do not modify the support system. With loaded driver’s seat, the dimension 90 mm between strap (1) and seat must be observed to ensure safe working con- ditions.
Page 48
Operating Instructions for the (Automatic) Support System Before travel starts, the function of the support system must be checked. The stop knob (2) must not be locked. – Sit down – Turn the switch key to "On". After having released the parking brake, both safety straps on the left and right side close and lock automatically.
Adjusting the steering column – Release steering column lock (4) and push steering column forward or backward to desired position. – Retighten steering column. Providing operational readiness – Unlatch master switch (10). To do so: Push in rocker switch (s) and pull upwards (r) until the master switch noticeably latches.
