3.0 Connection to a Dust Extraction System
This machine must be connected to a compatible dust extraction unit using a
suitable size and grade of vacuum hose.
Wood dust can be harmful to health by inhalation and skin contact, and concentrations
of small dust particles in the air can form an explosive mixture. Prevention or control of
wood dust exposure should as far as is reasonably practicable, be achieved by measure
other than the provision of personal protective equipment.
Employers have duties under the Provision of Use of Work Equipment Regulations 1998
(PUWER) and the Control Of Substances Hazardous To Health Regulations 1988 to carry out
an adequate assessment of the possible risks to health associated with wood dust
particularly when machining hardwoods, and if necessary seek expert advice as to the
method of dust extraction.
The minimum recommended air volume required to effectively exhaust this machine at
20m/sec is 1400 Cubic Metres per Hour.
A 150mm-dia outlet is located at the rear of the machine base. Provision is also made for
extraction from above the sawguard, simply remove bottom of the 50mm dia connection
point.
Always switch the dust extraction system on before switching on the machine.
4.0 Electrical Installation
All electrical wiring should be carried out by a fully qualified electrician and in
strict observance of the safety instructions.
Please follow these directions when connecting to the mains:
• The motor, starter, and isolator have been wired in at the factory and tested
before despatch. All that is required is to connect the power supply to the
isolator.
• Check that the supply details on the motor nameplate correspond with the site
supply.
• It is important that the correct cable size is used to avoid a voltage drop at the
motor terminals. If the motor is operated on a voltage outside, plus or minus 6%
of the spot voltage, then premature failure will occur.
• Do not wire single-phase machines into a 13 amp plug socket.
• It is important to check rotation of the sawblade which should be clockwise
when viewed from the left of the machine.
Should you encounter problems on start up please refer to the trouble shooting checklist
provided in the Maintenance Instructions.
