Fully depress the F and R accelerator pedals with the brake pedal released.
CAUTION: Rotating wheels.

yes

no

Motor reaches

maximum speed.

E

Install LP gauge with adapter III to ports Y and Z of remote control. Bridge the
footbrake microswitches and start the engine with the brake released.

Δ

p is 12 bar minimum.

Install banjo bolt 1.17 with plug at ports E and F of the travel control unit. Repeat
the test.

Clean and re-install nozzles in ports YF and ZF. Repeat the test.

See "Hydraulic speed
control".

no

yes

Pressure at

one gauge rises quickly to

value obtained at port F, while pressure

at second gauge lags for a

long time.

Valve (33) (13 bar) dirty
or setting incorrect.
Clean or correct the
setting.

Fault in travel control unit.
Possible causes: Valve
(47) sticking in open
position. Setting of valve
(46) (brake shaft)
incorrect. Valve (44) (11
bar) dirty or setting
incorrect.
