Description of the machine and its parts

Brush cutter BDR-620D, DR-620DB (Pict.2) is built on a steel frame, to which all important parts of the machine are attached. All controls (1,2 and 4) are
placed on the handlebars. Handlebars are attached to the frame with a bolted connection (3) and their height is adjustable into 3 positions. Handles (12) secure a
firm grip and machine handling during work. On the left side of the handlebars, there is the wheel drive clutch lever (2) which controls the movement of the
machine in forward direction. On the right side, there is lever (1) of the disc drive clutch for turning the cutting disk drive on (off). Both control levers return to
their original position when the handlebars are released in a critical situation and disconnect the engine power transfer. The cutting disk is equipped with an
automatic brake 53 which stops the disk. Engine speed is controlled with an accelerator lever (4). The wheel drive is controlled by worm-gear unit with a belt
clutch which provides fluent power transfer onto the wheels (15) (the machine does not start with a jump). The gearbox and clutch are covered by a plastic
gearbox cover (16). There is the cutting disk (7) with four steel blades (8) in the front part. The attendant is protected against flying parts of the cut stand by
plastic cover (10) and cutting disc steel cover (9) which meet the EN 12 733 standard. A detachable side screen (6), which is attached with a bolted
connection (5), controls the line spacing.

Assembling the machine

 As part of the pre-sale servicing, ask your dealer to unwrap the machine and give you a brief training on how to use it!
Places for holding the cutter while removing it from the box (see Pict.1): by the cutting disc in the front (4), by the machine frame tube in the back (1).
 Never attempt to lift the assembled machine by its front plastic cover. The cover will not support the machine's weight.

Assembling procedure

Use the following procedure for assembling the machine: (It is advised to assemble the machine with a second person's assistance)
1) According Pict.1 - take the disc cover (3), bag (6) and a side screen (2) out of the box. Pick the machine up by its lift points in front (4) and
back (1) and take it out of the box.
2) According Pict.2 - dismount the bolted connection (3) on both sides of the frame, take off the handlebars, turn them around and put them on the
frame as shown in the picture (choose one of the 3 holes in the handlebars to set their height). Re-tighten the bolted connection firmly with your hand.
Control lever cables must not be crossed - this shortens their lifetime!
3) Take the draw bands out of the bag and tighten brake cables to the handlebars where the upper bending of the handlebars tube ends. Two pieces of
draw bands are sufficient for cable tightening.
4) Mount the left (9) and right (10) covers on the steel disc cover (8) by the help of M6 bolts, M6 nuts with flat washers.
5) Dismount the self-locking nuts
that the holes fit in the screws in the frame, and the narrowed part of the cover is pushed in under the engine plate. Put the washers and self-locking nuts
M5 back on the screws and tighten them.
6) According Pict.1 - put the rear (shorter) screen (7) on the shorter arm of the screen holder (2). Put the side (longer) screen (7) on the longer arm of
the screen holder (2). Put the clamp bands (2 pcs) through the holes in the screen holder and draw both bands to fix both screens.
7) According Pict.2 - unscrew the fastening bolt (5) so that the side gate (2) can be easily pushed into the frame opening. Tighten the fastening bolt
with your hand and check that the side gate does not fall out spontaneously.
