After Digging; Turning Off The Machine - Garbin TZ S Use And Maintenance Instructions

TRENCHER
THE TYPE OF TRENCH DEPENDS ON THE TYPE OF GROUND AND THE EQUIPMENT MOUNTED
ON THE MACHINE. IT MUST BE PERFORMED IN TOTAL OBSERVANCE OF THE DESIGN
TECHNICAL SPECIFICATIONS PROVIDED BY A QUALIFIED PROFESSIONAL.
MACHINE STATUS:
Engine off with the equipment raised a few centimetres from the ground, located in the digging site and
aligned with the outline of the trench to dig;
PROCEDURE:
1) Move the cam stroke recovery ratchet engage-disengage lever to "engaged" (see fig.2 pos. 13)
to lock the machine as soon as it starts digging. This opposes resistance to the trench chain
when it sinks into the ground.
2) Check that the tow ratchet engage-disengage lever (see fig.3 pos.16) is set to "forward" and
therefore disengaged, if not the machine begins to move in the work direction as soon as the
engine is turned on and revved up.
3) Turn on the machine (see para 7.5), rev the engine and engage the trench chain.
4) Slowly lower the digging equipment to the required depth using the lifting and lowering jack
(see fig.2 pos. 9), taking care to avoid any projected material.
5) After resuming the correct operating posture (see para 7.4) move the machine along the
trench (see fig.9) engaging the tow ratchet with the lever (see fig.2 pos.9) and dig the trench as
required
POSITION THE MACHINE SO THAT AT EACH STEP THE DIGGING PORTION IS EQUAL TO THE PREVIOUS
ONE, WITH NO SUDDEN JERKS OR JOLTS, IN ORDER TO ALLOW THE TRENCH CHAIN TO TURN FREELY
AND THE ENGINE TO MAINTAIN A CONSTANT NUMBER OF RPM'S. CONSIDER THE TYPE OF TERRAIN
AND THE TYPE OF TRENCH, ALWAYS IN OBSERVANCE OF THE DESIGN TECHNICAL SPECIFICATIONS
PROVIDED BY A QUALIFIED PROFESSIONAL.
IT IS STRICTLY FORBIDDEN TO MAKE SUDDEN CHANGES IN FORWARDS DIRECTION DURING DIGGING
OPERATIONS.
6) After digging turn off the machine and raise the trench jib.
ALWAYS TURN THE MACHINE OFF BEFORE ADJUSTING IT. BEWARE OF RESIDUE RISKS (SEE PARA 6.5).

7.7.1- AFTER DIGGING

1) Decelerate the engine using the accelerator control (see Fig.3 pos.13) to stop the trench chain from
turning.

7.8- TURNING OFF THE MACHINE

1) After allowing the engine to idle for a few minutes, turn it off by releasing the red Safety device for stopping the
engine lever(see Fig. 2 pos. 1) and turning the engine ON-OFF switch to OFF (see Fig.2 pos.15).
2) Raise the trench jib using the lifting and lowering jack (see Fig.2 pos. 9)
3) Put the machine in the "Machine off" condition (see para 2.2.2).
