INTENDED USE
This chainsaw is designed for cutting branches, trunks,
logs and beams of a diameter determined by the cutting
length of the guide bar. It is only designed to cut wood. It is
only to be used outdoors, by adults.
Do not use the chain saw for any purpose not listed above.
This chain saw is not to be used for professional tree
services. It is not to be used by children or by persons
not wearing adequate personal protective equipment and
clothing.
RESIDUAL RISKS
Even when using the chain saw as intended, there remains
a residual risk of harm which cannot be fully prevented.
The following list of potential hazards should be read and
understood. You should pay extra attention and care to
these items to reduce the risk of occurrence or injury.
• Contact with exposed cutting teeth and saw chain.
• Access to rotating parts (the saw chain)
• Unexpected, abrupt movement (kick back) of the guide
bar.
• Flying chain parts (thrown off or broken)
• Flying material (cut from the work piece)
• Inhalation of saw dust
• Loss of hearing if no hearing protective equipment worn
during use.
PREPARATION
WARNING! If any parts are damaged or missing do not
operate this product until the parts are replaced. Failure to
heed this warning could result in serious personal injury.
WARNING! Do not attempt to modify this product or create
accessories not recommended for use with this product.
Any such alteration or modification is misuse and could
result in a hazardous condition leading to possible serious
personal injury.
ASSEMBLY
Mounting the guide bar and saw chain
The guide bar and chain are supplied separately.
WARNING! Ensure the saw is unplugged from the power
supply before starting assembly operations.
• CS-1840: Unscrew the guide bar fixing knob and
remove the sprocket cover. (Fig. 1)
• CS-2040: Unscrew the chain tension locking knob and
remove the sprocket cover. (Fig. 2)
• Gear the saw chain to the sprocket while fitting the saw
chain around the guide bar, mount the guide bar to the
unit. (Fig.3)
Note: Pay attention to the correct direction of the saw
chain. The running direction is marked on the chain bar.
(Fig.4)
• CS-1840: Re-place the sprocket cover and tighten
gently with the guide bar fixing knob.

Tightening The Saw Chain
CS-1840:
1. While holding up the tip of the bar, adjust the chain
tension by turning the chain tension adjust screw. Turn
clockwise to tension the chain, or turn counterclockwise
to loosen. (Fig. 5)
2. Tighten the guide bar fixing knob securely with the
bar tip held up. Then check the chain for smooth
rotation and proper tension while moving it by hand. If
necessary, readjust with the sprocket cover loose.
CS-2040:
1. While holding up the tip of the bar, adjust the chain
tension by turning the chain tension adjust knob. Turn
clockwise to tension the chain, or turn counterclockwise
to loosen. (Fig. 6)
2. Tighten the chain tension locking knob securely with
the bar tip held up. Then check the chain for smooth
rotation and proper tension while moving it by hand. If
necessary, readjust with the sprocket cover loose.
Tips: A new chain will expand in length in the beginning of
use. Check and readjust the tension frequently as a loose
chain can easily derail or cause rapid wear of chain itself
and the guide bar.
OPERATION
Switching ON and OFF
1. Connect the tool to a mains power supply.
2. Depress the safety switch while squeezing the trigger
switch. (Fig.7)
3. Once the chain saw is running, the safety switch can be
released but the trigger switch must be held in.
4. If the chain saw does not run, the chain brake must
be released via the front guard (read the sections
"RELEASING THE CHAIN BRAKE").
5. Release the trigger switch to stop the tool.
Chain Lubrication
To prevent excessive wear, the saw chain and guide bar
must be evenly lubricated during operation. This unit
is equipped with an in-built auto lubrication system which
automatically supplies oil to the saw chain and guide
bar. NEVER work without chain lubrication.
WARNING! If the chain runs dry, the entire cutting
apparatus will quickly become severely damaged. It is
therefore important to check both chain lubrication and the
oil gauge before every use.
1. Before commencing work, check the oil gauge to
ensure there is sufficient oil. (Fig.8)
2. Never use the saw when the oil level is below the "Min"
mark.
Chain Lubrication Test (Fig.9)
1. Hold the chain saw above the ground. Be careful not
to allow the chain saw to touch the ground. For safety
reasons it is best to keep a clearance of at least 20cm.
2. Switch on the chain saw. If you now see growing traces
of oil, the chain lubrication system is working correctly.
3. If there are no traces of oil at all, try cleaning the oil
outlet, the upper chain tensioning borehole and the oil
duct, or contact your customer service centre.
