Cooling water supply
An electric water pump (15) in the water pan (5) provides the cooling water supply and transports
the cooling water from the water pan to the cutting wheel. A sufficient water supply results in a
longer service life of the cut-off wheel and dust binding. The water supply can be adjusted via the
tap on the cut-off wheel protective cover. The water pump must never run dry. The water pan can be
emptied via a drain plug (16).
Electric motor and switch-plug combination
Electric motor with 2,2kW. The motor has a thermal overload protection which trips if the motor is
overheated. The machine can only be restarted when the engine temperature has dropped and is
within the operating temperature range.
Switch-plug combination (12) with built-in undervoltage release which prevents the motor from
restarting after a power failure. After a power failure, the machine must be restarted manually. The
switch is equipped with an emergency stop function. After actuating the emergency stop flap, it locks
and immediately disconnects the motor from the power supply so that the machine comes to a
standstill. A restart of the machine is only possible after unlocking the emergency stop flap.
Laser
The laser (19) is electrically connected to the electric motor, switch-plug combination (12) and
switches on as soon as the motor is running. The laser is mounted at the beginning of the guide rail
and shows the exact course of the cut.

Functional description
The bridge saw is exclusively intended to cut building materials in the sizes specified under
Technical data.
The responsible operating personnel places the products on the machine by hand.
Fix the cutting head to the desired cutting depth by means of the cutting head handle and locking
lever.
Only move the cutting head over the attached handles.
By pressing the main switch, the machine starts the electric motor as well as the laser and the
cutting disc starts rotating immediately. The water supply must then be switched on separately via
the water pump switch located below the main switch. The water supply can be adjusted via the
water tap on the cut-off wheel guard.
The cutting head is pulled slowly through the material by the handles until the rear stop point of the
cutting head is reached. The cutting speed of the cutting process is controlled manually.
When the cutting process is finished, the motor is switched off via the main switch, the water supply
is interrupted by pressing the switch of the water pump.
NOTE!
For design reasons, the emergency stop function flap is located directly above the main switch.
An impact on the outer function flap causes an emergency stop. By opening the flap on this
switch, the machine can be switched off via the main switch.
NOTE!
After switching on the machine, the cut-off wheel starts to rotate immediately!
