Preparing The Digger To Work; Mounting The Digger On The Tractor - Bomet Z655/1 Owner's Manual

aggregate the digger with recommended tractor classes equipped with standard ballasts of
front axle and rear wheels in accordance with data given in the technical characteristics of
the tractor. Air pressure, particularly in rear tires of the tractor should be equal in both wheels
and in accordance with the tractor's manual!
Before suspension of the machine, lower rods of the tractor's suspension system shall
be set in lower position at the same height (distance between joints and the ground is
minimum 200 mm). Rods set at the equal height from the ground facilitate mounting the
digger on the tractor.

4.5. Preparing the digger to work

Caution
It is forbidden for the operator to stay between the tractor and the machine at the
tractor engine running.
Preparation of a digger to operation in season and after storage period (e.g. after
winter) consists in checking its technical condition and most of all durability of connections of
working elements with the frame. In case of stating damage or worn elements it is necessary
to exchange them into new or regenerated ones. Otherwise, it can lead to reduction of the
machine work quality.
Before each starting operation of the digger, it is necessary:
- check screw connections, in case of backlash tighten the nuts, (pay particular attention to
screws where silent blocks are embedded),
- check firmness of pivot connections,
- check the condition of the topper and adjusting nuts,
- check the condition of sifting hoppers,
- check the condition of bearings on which the shaft and eccentrics are embedded,
- check the condition of welds on the frame and other welded elements of the machine,
- lubricate the digger in accordance with recommendations (see section "Lubrication
instruction").
CAUTION
All maintenance in the digger shall be performed before installing it on the tractor.

4.6. Mounting the digger on the tractor

- disassemble a tool drawbar from lower rods of the tractor three-point suspension system,
- drive to the machine frame close enough with the tractor,
- turn off the tractor engine, remove the key from the ignition switch and pull
handbrake,
- install tractor lower rods onto the digger studs and secure them with typical cotter pins,
- using a pivot, link the upper connector of the tractor with the digger frame rack and secure
