Operating instructions
It is recommended to travel forward slowly when starting work in order to maintain
the correct speed of the blades. Adjust the angle of the saw to present the branches
approx 90' to the blades. Always ensure the blades are vertical to allow cut branches
to fall away. If a large branch is approaching adjust the working height to ensure it
meets the centre of a blade.
Do not use horizontally there is a danger the weight of the cut braches will bend the
blades, however 45' is permitted for trimming material up to 40mm diameter.
The Quad saw will cut up-to 100mm maximum, branches over 80mm must be cut
one at a time, pausing forward travel to allow the saw time to cut each branch.
In the event of small twigs or debris jamming the saw blades, stop the machine
immediately and clear the blockage with a suitable tool.
Ensure there is a skid mounted on the bottom of the saw attachment to protect the
lowest blade from striking the ground
ensure the hydraulic motor is primed with oil and the case has filled with oil, via the small hose
connection. Failure to fill the motor case with oil will lead to seizure due lack of lubrication.
Note
To change rotation of motor exchange the position of the pressure/returns hoses and
the anti-cav valve with the plug.
