–
Pull and turn the knob (46), insert the 3
as the stop, aligning the hole in the end of the rod with the pin knob.
Release the knob (46) so the wheel (41) can act as a support on the opposite rail so
the assembly is stable and able to slide along the rail; the rod can be fi tted to the
4 carriage from either side for convenience in selecting the direction of work.
–
Pull and turn the knobs (12 and 16) at the base of the pump unit.
Lift the pump unit by means of the handles (01) and handlebar (08).
Rest the pump unit on the clamp unit and align the pins (20) with the relevant locating
5 holes on the under side of the pump unit. Release the knobs (12 and 16) for locking.
–
Restore the oil delivery/return hydraulic circuit, connecting the fl exible hoses by

position.
Note: the two springs diff er from one another.
7.1.5) Maximum pressure valve (Ref. to Fig. 24)
The hydraulic pump features a maximum pressure
valve, factory set and sealed at 42 Mpa.
NEVER CHANGE THE MAXIMUM PRES-

A
To check correct valve setting, a special pressure
testing gauge is available (see § 8).
7.2) Routine maintenance of the engine
Checks and periodical assistance are indispensable to ensure smooth engine operation.
Refer to the "HONDA owner's manual" supplied with the machine, for the following operations:
– Oil change
