Fig. 26
Fig. 26 shows a drawing of the chain drive of the back wheel. The tensioning wheel
(1) can be found behind the back wheel. Remove the side cover to access the
tensioning wheel (1) and adjust it.
The chain clearance must be approximately 15 mm (0.6”) when moved manually.
Adjust the chain tension by loosening the bolt/nut (2) of the tensioning wheel one
turn, pushing the tensioning wheel into the groove (3) up and re-tightening it.
@ Avoid damage by NOT tensioning the chain too tightly.
@ Do not apply too much lubricant when lubricating the chain. This will ensure that
leaks and, therefore, any tracks in the field, are avoided.
16.9 Adjusting the pressure of the hydraulic system
The pressure of the hydraulic system is
controlled through a pressure relieve valve
that has been added to the main valve, see
fig. 27.
The system pressure can be adjusted at
approximately 120 bar (1700 psi).
If the Verti-Drain
®
cannot go up anymore, an
adjustment or a check may be required.
The system pressure can be changed by
loosening the check nut (1) and tightening or
loosening the screw (2) more.
@ Do not touch this adjustment when
everything is operational.
@ Always measure the system pressure
when changing the adjustment.
* The system pressure may never be more
than 140 bar (2000 psi).
* A higher pressure may damage the
system and/or cause injuries.
