MAINTENANCE PLAN 4.7.1.j CHECKING AND ADJUSTING THE BRAKE PEDAL STROKE This check must be carried out when operating on the braking unit in order to eliminate any trouble. To check and adjust the brake pedal stroke, proceed as follows: 1 - Insert the connection pin (1) in order to couple the pedals. 2 - By acting on the end-of-stroke rubber pads (2), position the pedals in correspondence with measure “A” - 325 mm; lock the pads in this position. (Use a 13 mm spanner). 3 - Lower the pedals to the measure “A” - 306 mm; adjust the po- sition of the microswitches (3) by bringing them near the ped- als and lock them. (Use a 17 mm spanner).
1 RWA13980 4 - Further lower the pedals to the measure “A” - 294 mm and adjust the brake pump rods (4) until they touch the pumping pistons; lock them in this position. (Use a 22 mm spanner). 2 3 4 RWA13990 A RWA16470 4.7.1.k ADJUSTING THE AUTOMATIC RETURN OF THE FRONT BUCKET TO THE DIG- GING POSITION (0.078-0.157 in) The device for the automatic return of the front bucket to the dig- ging position automatically brings the front bucket to the loading position when it is lowered to the ground.
The sensor is posi- tioned on the right dumping cylinder and determines the hori- zontal position of the bucket with respect to the ground after the bucket dumping control has reached the end of stroke and the electromagnet of the distributor rod has been operated (see “3.3.5 pos. 4 LOADER CONTROL LEVER”). The sensor must be positioned at a distance of 2-4 mm (0.078- 0.157 inches) from the sliding rod. RWA34420 173
