Speed of the blade (m/min) 45
Direction of rotation of the blade drive
shaft to the right
Weight (kg) 23
Earthing
This metal hacksaw is a single-insulated tool, the
earthing circuit therefore being designed to protect you
from electrical shocks. The earthing circuit is made once
you have connected the machine to the appropriate
mains power supply. You should therefore provide a
mains power system for this machine that protects you
from electric shock hazard.
Protecting the motor
WARNING:
To prevent any electrical hazard, fire hazard or
damage to the tool, use the appropriate circuit
protection device. Your saw is wired at the
factory to run on 230 V current. Connect it to 10
Amp 230 V mains power supply and use a 10
Amp time delay fuse or circuit breaker. To
prevent electric shock or fire, immediately
replace the power supply cable if it is worn, cut
or damaged in any other way.
DANGER
To prevent electric shock:
1. Only replace the power supply cable and plug
with
identical models supplied by the
manufacturer.
2. Do not use the saw in rain or on wet ground.
This tool is only intended for home use,
indoors.
1. Connect this tool to a 10 A, 230 V power supply circuit with a 10 A time delay fuse or circuit breaker.
The use of a fuse with the incorrect amperage could damage the motor.
2. If the motor does not start, immediately release the trigger. UNPLUG THE TOOL. Check the the blade runs
freely. If this is the case try to start the motor again. If the motor still does not start, refer to the “Motor
Troubleshooting table"
3. If the motor suddenly locks when cutting wood, release the trigger, unplug the tool and remove the blade from
the wood. Then try to restart the motor and finish the cut.
4. The fuse may "melt" or the circuit breaker trip if:
a. The motor is overloaded - there is overload hazard in cases of too rapid advancement, or of stopping and
starting too frequently in a short period of time.
b. A voltage up to 10% maximum higher or lower than that indicated on the nameplate can withstand normal
loads. In case of heavy loads, however, the voltage (due to a wire whose gauge is too small or one that is
too long in the power supply circuit) may fall to the point of not allowing the motor to function. Always
check the connections, the load and the power supply circuit if the motor malfunctions. Check the wire
gauges and lengths in the Wire gauge table below.
5. Most problems with the motor can be attributed to incorrect or loose connections, overload, insufficient voltage
(due, for example, to a wire with too small a gauge in the power supply circuit) or a wire that is too long in the
power supply circuit. Always check the connections, the load and the power supply circuit if the motor
malfunctions. Check the wire gauges and lengths in the Wire gauge table below.
Wire gauges
Use of an extension lead results in a loss of power. To minimise and avoid overheating and motor breakdown of
the motor determine the minimum gauge (the cross section) of the extension lead wires using the table below. For
circuits more than 40 m away from the power supply cabinet, the gauge of the wires should be proportionately
increased, in order to deliver sufficient voltage to the saw motor.
Cable Length Wire gauge recommended for 230V.
Up to 15 m 1,5 mm²
15 to 40 m 2,5 mm²
