The Atlas Copco LS 14 Cut-off Saw and the LS 16 Cut-off Saw are sturdy and reliable saws
designed for working together with Atlas Copco power packs.
The Cut-off Saw is available in both a 14” and a 16” version. The saws are designed for cutting in all directions with discs both for dry and water flushed cutting. An aspirator can be connected to the flange socket of the guard.
The Atlas Copco LS 14 Cut-off Saw and the LS 16 Cut-off Saw are delivered with 2 m 3/8”
tail-hoses with ½” Flat-Face quick-release couplings.
The direct driven hydraulically powered design provides consistent speed and torque. It also
enables underwater cutting.
5 English
For precise and clean cutting jobs on roads, sidewalks and floors, the Atlas Copco LSC Cart
for the Cut-off Saw is recommended. The use of the Cart gives a better working posture, and
the cutting depth can be adjusted by means of an arm at the front of the Cart. The Cart is
equipped with water kit. The Cart is not standard equipment.
A separate water kit with pressure tank is also available (see the spare parts list).

The following checks should be made
each time you start to use the Cut-off Saw.
All these checks concern the serviceability
of the Cut-off Saw. Some concern your
safety.
1.
Check that the disc is in a good condition and properly attached
2.
Clean all safety decals. Replace any
that are missing or cannot be read
3.
Inspect the hoses generally for signs
of damage
4.
Check for fluid leakages
5.
Ensure that the hydraulic couplings
are clean and fully serviceable
6.
Ensure that any power source you
plan to use is compatible with the
model of the Cut-off Saw you are
using. See the section Technical
data. Atlas Copco recommends using an oil flow divider, if the flow
from the power source can exceed
the maximum allowed oil flow (see
the spare parts list)
WARNING
Do not exceed the maximum flow
for the Cut-off Saw as this might
lead to failure of the disc and
damage of the tool.
7.
Connect the hoses
8.
Mount the Cut-off Saw in the Cart (if
a Cart is used)
9.
Start the power source
10.
Activate the water supply or aspirator if used
11.
Place the Cut-off Saw at a right
angle on the surface to be cut and
activate the trigger lever

1.
Release the trigger. Keep a firm grip
on the Cut-off Saw, until the disc has
come to a complete stop
WARNING
The inertia of the disc is very high.
The Cut-off Saw could move and
thereby injure persons or equipment if placed on the ground before
the disc has come to a complete
stop.
2.
Stop the power source
3.
Disconnect the hoses and fit the
protective caps to the quick-release
couplings

A poorly maintained Cut-off Saw is a hazard. Doing regular maintenance and lubrication jobs as listed in these schedules will
help keep the Cut-off Saw in a safe working condition.
Apart from the daily jobs, the schedules
are based on the operation hours of the
Cut-off Saw. Keep a regular check of
hours in use. Do not use a Cut-off Saw
that is due for regular service. Rectify any
defects found during regular maintenance
before clearing the Cut-off Saw for use
WARNING
Maintenance must be done only by
suitably qualified and competent
persons.
Before doing any maintenance,
make sure that the Cut-off Saw is
safe and correctly sited on level
ground.

WARNING
Fine jets of hydraulic oil at high
pressure can penetrate the skin. Do
not use your fingers to check for
hydraulic oil leaks. Do not put your
face close to suspected leaks. Hold
a piece of cardboard close to suspected leaks and then inspect the
cardboard for signs of hydraulic oil.
If hydraulic oil penetrates your skin,
get medical help quickly.
Note: Check tightness of nuts, bolts,
screws and hose fittings after the
first days of operation and thereafter
in accordance with the maintenance
