NEW BRUSHCUTTERS / TRIMMERS –
DS 240 S AND DS 240 T – EURO 1
Emak presents its new range of the word’s most lightweight brushcutters, establishing a new benchmark in their
class.
The DS 240 S and DS 240 T range was developed for demanding private users who need to use a brushcutter
regularly and are looking for a tool that is:
- lightweight: easy to handle and guaranteeing lasting eciency,
- simple: easy starting, operation and maintenance
- compatible with fatigue-free operation
To meet these requirements, these new brushcutters use a series of technical solutions that are normally stan-
dard features only on professional models. Special attention was devoted to compliance with the most stringent
anti-pollution regulations (Euro 1) and compatibility with alkylate petrol.
Thanks to the new super economy engines, these brushcutters will provide more than 50 minutes of continuous
operation before refuelling.

PERFORMANCE AND ENGINEERING
• 21.7 cm³ 1.2 HP (0.9 kW) 2-stroke engines, in compliance with
regulations (Euro 1), compatible with alkyl petrol and featuring
a high linear torque curve even at low revs.
•Piston with 2 rings, diecast cylinder with Nickel plating, forged
con rod and crankshaft (Fig. 1): guaranteeing an extremely rug-
ged and durable engine.
• Digital coil with electronic control (Fig. 2) and revs limiter: for
easier starting, improved performance thanks to uniform com-
bustion, and reduced fuel consumption.
• Aluminium cover and clutch support (Fig. 3): optimised and
reduced weight of the tool while imparting high strength and
lasting reliability.
• Ø 24 mm aluminium tube (Fig. 4a), nylon sheath (Fig. 4b), 7 mm
internal rigid shaft (Fig. 4c) and aluminium bevel gear pair with
M 10 male drive pin (Fig. 4d), for unimpeded power transmis-
sion.

OPERATOR DESIGN FEATURES
• A graphic representation of starting operations facilitates engi-
ne starting even for less expert users (Fig. 5a).
• Air purge primer (Fig. 5b) visible on the engine cover ensures
easier access and operation.
• The on/o switch (Fig. 5c) returns automatically to the“on”po-
sition after each stop (always on).
• Choke lever integral with half-throttle setting for fast and easy
starting.
• “Easy on” device (Fig. 6) composed of a double spring in the
starter cover combined with driver with two ratchets means
reduced force with each pull and fast starting with fewer rope
pulls.
• Filler cap with two grips (Fig. 7a) (side and top) and tank ller
neck (Fig. 7b) in vertical position for easier refuelling.
• Transparent fuel tank (Fig. 7c) for instant view of the quantity of
fuel remaining.
• Innovative 130 mm Ø “LOAD & GO” line head (Fig. 8): for strai-
ghtforward line replacement - just 20 seconds to rewind the line
and resume work.

OPERATING BENEFITS
• Built-in antivibration system: greatly reduced vibrations felt by
the operator during use of the tool (Fig. 9).
• Ergonomic loop and handles: clad in soft rubber (Fig. 10a-b) of-
fer an anatomic and comfortable grip of the tool in all operating
conditions.
• The twin version with ergonomic aluminium handlebar featu-
res an easy-to-use adjuster knob (Fig. 10c).
• 150 mm drive tube: the operator is always able to maintain an
erect posture.
• New stone guards for ecient protection against projected de-
bris.
In addition, simply removing the skirt with line cutter knife (Fig.
11c) makes the line head suitable for use with a metal blade.
• Harness, supplied as standard (Fig. 12a S version), (Fig.12b T
version) is easy to adjust and imparts greater freedom of move-
ment allowing improved weight distribution in accordance with
the operator’s stature.

SERVICE FRIENDLY
• Generously sized cloth air lter: guarantees high ltration e-
ciency and easy maintenance (Fig. 13a).
• Filter support (Emak patent) with anti-backow element (Fig.
13b), (prevents the lter from becoming fouled by fuel) for lon-
ger operation between lter maintenance procedures.
• Filter cover accessible without tools by means of specic knob
(Fig. 14a): facilitates air lter inspection and cleaning.
• Silencer protection (Fig. 15a) separate from the engine cover,
removable by means of 3 screws: provides rapid access in the
case of maintenance.
• All screws are of the TORX head type, to allow the use of a sin-
gle tool for most maintenance procedures (Fig. 16) .
