14.Chock up the wheels to prevent moisture damage
and deformation of the tyres. Tyre blacking can be
applied to the tyre walls to preserve the rubber.
15.Engine preservation is carried out as descried in the
engine manual.
16.To protect against dust the sprayer can be covered
by a tarpaulin. Ensure ventilation to prevent conden-
sation.
Preparation after off-season storage
After a storage period the sprayer should be prepared
for the next season the following way:
1. Remove the cover.
2. Remove the support from the wheel axle and adjust
the tyre pressure.
3. Wipe off the grease from hydraulic ram piston rods.
4. Fit the pressure gauges again. Seal with Teflon tape.
5. Prepare engine according to instructions in the en-
gine manual.
6. Check all hydraulic and electric functions.
7. Empty the tank for remaining anti-freeze.
8. Rinse the entire liquid circuit on the sprayer with
clean water.
9. Fill with clean water and check all functions.
Emergency operation of the sprayer
The boom
In case of power failure the boom can be operated
manually by pressing the individual buttons on the sole-
noid valves.
Remove the protection box of the solenoid valves at the
boom. Lock the by-pass valve. The boom can now be
operated by pressing the individual buttons on the sole-
noid valves.
The problem may be due to a blown fuse.
EC operating unit
In case of power failure it is possible to operate all func-
tions of the operating unit manually. First remove the
fuse in the junction box. Now manually turn the emer-
gency control knobs.
Towing
In emergency situations the machine can be towed a
short distance. In case of a engine break-down on pub-
lic road, and the machine must be pulled up on a truck.
IMPORTANT! Never attempt any towing unless
the parking brakes in all 4 wheel motors are re-
lieved mechanically and the high pressure relief
valves on the hydrostatic pump are relieved! Failure to
do so will damage the transmission.
Hydrostatic pump
1. Remove the dust plug
2. Loosen the counternuts
A
3. Loosen the high pressure valves B a few turns CCW
with an Allen key
The machine can now be towed.
IMPORTANT! Towing must only take place in emer-
gency situations. Max. towing distance is 15-20 m . Max.
towing speed is 5 km/h . Exceeding these limits can
damage the transmission.
When the towing is finished the transmission must be
set back to normal again.
1. Loosen the nuts and remove the brake relief yokes,
screws and nuts from the wheel motors
2. Fit the dust plug to the wheel motors again
3. Fit two 600 bar pressure gauges to the main pres-
sure measure outlets
4. Activate the parking brake
5. Start the engine set at 2000 r.p.m. and push the pilot
lever forward
6. Adjust the high pressure relief valve to 420 bar
7. Set the pilot lever in reverse and adjust the second
relief valve to 420 bar
8. Set the pilot lever back to neutral again
9. Release the parking brake and test the transmission
function
Hydraulic wheel motors
1. Remove the protection rubber dust plug
2. Fit the screw
3. Fit the yoke
4. Tighten the nut a few turns in order to relieve the
spring pressure. Do this on all 4 motors.
