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.

valve housing. Carefully install accumulator onto top of
valve housing. Make sure decals (Items 47:2, 47:1)
are facing forward and securely attached to accumulator.

valve body and into base of accumulator. Tighten to a
torque of 40 ft-lb.
Wear eye protection. Keep hands and face
away from gas valve.
7.
Charge accumulator with dry Nitrogen (see TEST
NO. 3: Accumulator Pre-Charge Pressure and Adding
Dry Nitrogen in the Testing section).
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.
Charged accumulators cannot be shipped via
air freight.
