Accumulator Service (Fig. 44, 45, 46)
The accumulator piston seals will wear over a period of
time. As seals wear, the accumulator will require more
frequent recharging and eventually, it will not hold gas.
1.
Park machine on a level surface, stop the engine,
engage the parking brake and open the hood.
DANGER
Charged accumulators contain high pressure
nitrogen. Nitrogen is the only gas to use for
accumulator charging. Installing IMPROPER
gases in an accumulator can cause an EX-
PLOSION AND DEATH. Charging requires
special tools and precautions. Charge ac�
cumulators in a well ventilated area. It is
recommended that the accumulator be
checked and charged by an Authorized TORO
Distributor.

Wear eye protection. Keep hands and face
away from gas valve.
Slowly open high pressure water bleed valve
before servicing any component connected
to high pressure water system. Opening the
high pressure bleed valve allows any trapped
water to escape from the system and also
allows accumulator piston to move to bottom
of accumulatorcylinder. Failureto open bleed
valve before servicing high pressure water
components can cause personal injury, DIS-
MEMBERMENT OR DEATH.
Figure 45
Charged accumulators cannot be shipped via
air freight.
2.
Slowly open the high pressure bleed valve allowing
any pressurized water to escape.
3.
4.
Remove protective cover from top of accumulator.
Attach and gently tighten special fitting of Charging
Tool (TOR4001) to inlet on top of accumulator.
5.
Close both valves on charging tool to prevent loss of
pressurized Nitrogen from accumulator.
6.
Rotate the jam nut (not the fitting) of the accumulator
valve two (2) turns counterclockwise as viewed from the
top. This opens the valve and pressurizes the tool and
gauge.
7.
Slowly open outlet valve on right hand side of charg-
ing tool to release pressurized gas from accumulator.
When gas stops escaping, disconnect the charging tool.
