Driving The Access Platform; Using The Drive Control Equipment; Using Drive Control Equipment (Starting The Diesel Engine From The Platform) - Kesla XS 190 Operation & Maintenance Manual

DRIVING THE ACCESS PLATFORM

Kesla XS 190 has hydrostatic power train, and all the drive and control functions can be
controlled from the platform. The power train has a continuous four-wheel drive and two
speed ranges. The low speed range is 0 to 1.8 km/h with the pulling force measured from
a stationary machine being 15,400 N; the high speed range is respectively 0 to 3.6 km/h
with pulling force 7,700 N. The brakes are disengaged when the hydraulic pressure in the
drive motors exceeds 30 bar, and are automatically engaged, when the pressure is less
than 30 bar. There are disk brakes in all wheels.

USING THE DRIVE CONTROL EQUIPMENT

Switch on the power with the starting key. The key may be removed also when the power
is switched on. The keys should always be kept in one bundle.
Main power switch
Using drive control equipment (starting the diesel engine from the
platform)
Switch on the power – turn the key to ON and preheat the engine with the key in the
preheating position. Keep the preheating on as long as the preheat signal lamp is lit. In
cold weather, repeat the preheating procedure two to three times. Do not heat longer than
15 seconds at one go.
Start the engine with the key and let it run for a moment. Note! Do not run the starting
engine longer than 10 seconds at a time. Steer the Access Platform with the lever at the
extreme right, and drive the Access Platform with the lever on the left side of the steering
level. Choose the speed range with HI/LO selector. The low range has a considerably
higher traction force then the high range. Choose the steering mode with the three-mode
selector: four-wheel steering, crab steering or rear-wheel steering.
The wheels are centered by choosing four-wheel steering and turning the front wheels to
the middle position.
After this, the rear wheels can be turned separately with rear-wheel steering. Inaccurate
turning of the wheels may result from air in the system. The air can be removed by turning
the wheels fully to one direction and maintaining a full hydraulic pressure for a short while,
and then turning the wheels to the opposite direction. If there is a reason to suspect that
air has entered into the system, this operation should be carried out three times. The rear
wheel driving is the best steering mode at high driving speeds.
