4.1) Assembly of the machine
Select the rail to be worked on and the direction of operation, then assemble the machine as
follows, referring to fig. 4:
With knob (29) engaged and wheel (34) blocked, raise the clamp unit by means of
the handles (33) and rest this on the selected rail, positioning it in line with a
sleeper for stability.
Rest the support carriage on the track and then pull and turn the fastening/release
knob (48). Lift the clamp unit by means of the handle (21) and locate (19) pins fully
into their carriage housings as far as the stop.
Release the knob (48) to lock the clamp unit.

Pull and turn the knob (46), insert the 3rd wheel bar in the carriage housing as far
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 fitted to the
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
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 flexible hoses by
means of the quick couplings (09 and 10) to the respective connectors (25 and 24)
on the clamp unit.
Connect the brake release device (51) (ref. to § 4.1.1)

4.1.1) Braking device (Ref. to Fig. 3a, 3b, 3c, 5)
To run the machine along the rail, it is necessary to connect
the brake release device (51), proceed as follows:
– Introduce end part (A) into slot seat (B) located above
the rear wheel of the clamp unit ( Ref. to Fig. 3a) .
– Pull the handle (C) upwards, release it in position than
push until is locked ( Ref. to Fig. 3b and c) .
– Pressthehandle(45)toverifythecorrectengagementand
disengagement of release pin (P) from the wheel ( Ref. to
Fig. 5 and 3c) .
During the disassembly of the machine, before removal
of the pump unit, the brake release device must be disas-
sembled as follows:
– Pull the handle (C) and disconnect the end part (A)
from slot seat (B).

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
– Air filter assistance (see double-element type)
– Cleaning sediment from sump
– Spark plug cleaning; recommended plugs BPR6ES (NGK) or W20EPR-U (DENSE)
– Minimum carburettor setting
7.3) Long periods of inactivity
– Store the machine in a dry environment, and adequately protect it against accidental
damage and contamination (see § 8).
– For information on the combustion engine, refer to the "HONDA owner’s manual"
.
7.1.4) Changing the gas springs (Ref. to Fig. 23)
Replace the gas springs when required
as follows:
– Using a flat-blade screwdriver, lift the retention
collar at the end of the spring, pulling with force
at the same time to release the spring from its
locating pins.
– Fit the new spring on the same pins and press
withforceuntilthisisproperlyfittedintheoriginal
position.
Note: the two springs differ 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-
SURE VALVE SETTING AS THIS MAY CAUSE SERI-
OUS DAMAGE TO THE MACHINE.
To check correct valve setting, a special pressure
testing gauge is available (see § 8).

7.1.2) Topping up the oil in the hydraulic pump (Ref. to Fig. 19)
Periodically check the level of the oil in the hydraulic
pump. The oil should always be visible inside the
tank (03). If the level is low, top up with the specific
oil recommended:
– Unscrew the cap and add sufficient oil to fill the
tank; do not exceed the oil level.
– After topping up, tightly screw the cap back on.
Always use clean recommended oil, see § 1.
Do not use old or recycled oil.
Do not use hydraulic brake fluid.
7.1.3) Changing worklight bulbs
– Loosen the locking nut (Ref. to Fig. 20).
– Turn worklight upwards and remove the two
screws in the lens (Ref. to Fig. 21) using a screw-
driver.
–
Remove the faulty bulb and replace with another
having the same specifications: 12V - 21W
– Replace lens and tighten the two screws.
– Reset worklight to original position and tighten
the nut.
The light bulb power circuit is protected by a
fuse against overcurrents and short-circuits.
In case of a fault:
– Remove the 4 screws from the lid of the termi-
nal box (14) using a screwdriver.
– Pull out fuse carrier and open it (Ref. to Fig. 22).
– Replace faulty fuse with a new one with the
same specifications: 6,3A - 250V.
– Push fuse carrier back, replace lid and tighten
4 screws.

4.2) Moving the machine (Ref. to Fig. 4b)
To move the machine along the track, the rear part must be raised to prevent the clamps knock-
ing against the Fastclip.
1 - Pull and turn knob (29). The wheel arm will be freed.
2 -Slightly raise the machine by means of
handlebar (08); lifting will be made easier by
the two gas springs, then release the knob (29)
to lock the machine fully up.
3- Press brake release handle (50) against the
handlebar (08).
4- Push the machine along the rail.

4.1.2) Disassembly of the machine (Ref. to Fig. 4 and 4a)
To disassemble the machine:
– First lower the rear part and lock with pin
(29), block wheel (34) then reverse the pro-
cess described in § 4.1.
– Before disconnecting the pump unit, make sure
to have disconnected the hydraulic circuit and
the braking device; locate the hoses in support
(S) got on the frame of the pump unit.
If necessary, with the machine fully assembled and
the motor switched off, the clamps can always be
opened or closed manually.
NOTE: Under normal conditions, the time taken to
remove the machine from the rail is approximately
60 seconds.
FIG. 4a – SUPPORT

Before every use:
– Check wheel for resistance, wheel should not be free rotating.
– Ensure wheel is clean, removing any dirt or mud.
– Check for signs of damage.
Every 6 months:
– Check for excessive braking on wheel. Wheel should roll along track when pushed,
wheel will slide if excessive braking occurs.
Clamp unit wheel
Before every use:
– Check cable, linkages, springs and wheel for signs of damage.
– Check linkages are free moving.
– Ensure brake cable moves without resistance.
– With brake released, check that wheel rotates freely.
– Check that when handlebar lever is in the raised position, the brake is engaged.
– Ensure that wheel is clean of dirt and mud.
– Check that, before assembly, the wheel does not rotate one full turn in either direction.
– Ensure coupling is free of dirt and mud.
Every 6 months
– Check wheel pockets for excessive wear. If braking effectiveness is compromised,
replace wheel.
– Check extension spring (see figure) on brake release handle (50) are undamaged.
– Check for wear on pivots.
– Ensure fasteners are secure.
– Check for wear on coupling, parts should mate securely.
– Clean all moving parts and lubricate as required.
