Method for Long-term Storage
If the machine is not used for a long period of time,
follow the care procedure below:
(1) Run through all maintenance and inspection
items.
(2) Service problem locations, if any.
(3) Inspect the bolt and nut in each part and tighten
them if loose.
(4) Run the pump at low speed using freshwater and
circulate the water for 3 to 4 minutes to clean the
inside of the tank, piping, nozzle, etc. To prevent
damage caused by freezing, drain all liquid from
the spray pump and piping by removing the drain
plugs and running the pump idle.
Drain the pump and inside the pipe.
How to drain water
[1] Remove the drain plug from the spray pump.
[2] Remove the plugs at the tips of left and right booms.
[3] Disconnect the spray hose at the bases of right
and left booms to drain water.
(5) Remove the nozzle cap and drain water remaining
inside the nozzle.
(6) Clean the exterior of the machine.
(7) Change engine oil with new oil and operate the
engine for around 5 minutes to spread oil to each
part.
(8)
Be sure to keep the throttle lever in the “Low
speed” position.
(9) Fill up the fuel tank with fuel (diesel oil).
(10) Store each boom on the boom receiver.
(11) Use sandpaper, etc., to remove rust from areas
where paint has peeled, and apply a fresh coat of
paint.
(12)
Keep each cock in the “Open” position.
(13) Disconnect the battery cable or remove and store
the battery in a dark, dry place.
(14) The battery will self-discharge during storage, so
perform auxiliary charge once every month.
(15) Select a dry place for storage and cover the
machine with a sheet, etc., to prevent attachment
of dust, etc.
(16) Apply grease on the exposed part of each
hydraulic cylinder piston rod for boom actuation.
Before moving each hydraulic cylinder after
storage, wipe off the grease on the piston rod.
(If dust attached to the grease enters the cylinder
seal, oil may leak.)
Caution
The booms will drop gradually due to their dead
weights, so do not put objects underneath the
booms during a long-term storage.
