2.3.2 Description of the machine and its parts

Brush cutter DS-521D (Pict.3) 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
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.

2.4 User guide

2.4.1 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.

2.4.1.1 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), side and rear screens (7), screen holder (2) and parts of lower disk cover 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.3 - 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) Dismount the self-locking nuts
machine so 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.
5) 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.
