- Close the valve (1).
- Separate the hose (2).
- Open the coarse filter (3).
- Loosen the intake to the pump by moving the
plastic clamp to the left and pulling the white
plastic adapter from the pump housing.
- Open the valves in the ends (4) of the sprinkler
pipes.
- Allow the fluid to run out and run the sprinkler
pump for about 10 seconds.
Freeze protection
Freeze protection can also be achieved by connecting
a separate container, after dividing the hose, with
water mixed with glycol and running approx. 2 liters in
the system.
Check the emergency stop system pressure
Place the roller on a level base. The engine
must be switched off and the reserve/parking
brake knob pushed in for all checking and
adjustments on the roller unless otherwise
specified.
Check by pressing the brake pedal. Air pressure
should be 7.85 bar (114 psi). This is the maximum
pressure.
Do not move the roller before the system
pressure has reached its specified operating level.
