Installation
(contd.)
Fitting the Tree-Lopper to the excavator
Carry out a visual inspection of the Tree-Lopper and all the components. Check the packaging
for any damage which may have occurred in transit. If you discover anything is missing or
damaged please contact Bomford Turner Ltd. before you proceed any further.
The Tree-Lopper is supplied with a custom mounting bracket – as requested at time of ordering
to suit the excavator for which it is to be fitted.
Place the Tree-Lopper on level ground and with the cutting jaw facing away from the
excavator, move the excavator's arm over the Tree-Lopper and lower it into position. Align the
mounting bosses in the excavator arm & links with those of the Tree-Lopper (as in fitting a
bucket to the arm). Grease the pins and bushings prior to fitting and secure the pins in place
with the pin retainers.
Alternatively, the Tree-Lopper may have been supplied with a "fixed pin" bracket for picking up
with a hydraulic coupler. In this case, connect to the Tree-Lopper in the usual way with the
coupler - make sure that all necessary locking pins & security devices are fitted.

WARNING
Make sure all pin retainers & locking devices are installed correctly
Check the Tree-Lopper is fitted correctly by starting the excavator & raising the Tree-Lopper
clear of the ground. Operate the bucket crowd control slowly whilst checking that there is no
resistance or interference to movement. If there is any sign of a problem with the smooth
functioning of the Tree-Lopper contact Bomford Turner Ltd. DO NOT attempt to carry out any
modifications to the Tree-Lopper.
Δ
WARNING
In some instances, operation of the Tree-Lopper in certain positions may result in damaging
contact between the Tree-Lopper & the excavator's boom, dipper and/or the operator's area.
Extra care is required when operating this implement, particularly when used in conjunction with
a hydraulic coupler.
Hydraulic Installation
The Tree-Lopper requires one double acting hydraulic circuit to operate with 200 Bar pressure
available.
If your Tree-Lopper has been supplied with a rotator this will normally be operated via an electric
diverter valve which is attached to the mounting bracket, thus enabling operation of both shear &
rotate functions from one double acting circuit. The diverter valve is operated via a momentary
switch which is mounted on the joystick in the cab of the excavator; simultaneous operation of
both the switch & the auxiliary function will enable rotation. The cable for the switch can be tie-
