2. While pressing the centre red button (A) on the reel valve pull yellow plunger (B) away from the valve.
48
3. Start the engine and set the throttle to low idle. Lower heads by operating the Joystick or paddle.
48
4. Slowly turn the restriction valve knob (C) clockwise until the desired reel rotation speed is attained. It should be slow enough so that the reel will not throw off the backlapping compound as it spins.

6.17 SLINGING and jacking THE MACHINE
48
Slinging
48
When slinging the machine use the tie down loops front and rear.
48
Jacking
48
The machine has three jacking points, one at the rear chassis engine mount and two on
48
the front chassis wheel motor mounting.
48
6.18 Mowing on slopes
49
The mower has been designed for good traction and stability under normal mowing conditions. Use caution when operating on slopes, especially when the grass is wet. Wet grass reduces traction and steering control.
49
WARNING
49
To minimize the possibility of overturning, the
49
safest method for operating on hills and
49
terraces is to travel up and down the face of
49
the slope (vertically), not across the face
49
(horizontally). Avoid unnecessary turns, travel
49
at reduced speeds, and stay alert for hidden
49
hazards. To ensure best stability always load
49
the left hand storage rack first and cut with all
49
three units powered.
49
1. Always mow with the engine at full throttle, control forward speed using traction foot pedal to maintain proper cutting.
49
2. Use weight transfer control as required to improve weight distribution between decks and mower.
49
3. If the mower tends to slide or the tyres begin to mark the turf, angle mower into a less steep slope until traction is regained or tyre marking stops.
49
4. If mower continues to slide or mark the turf, the slope is too steep for safe operation. Do not make another attempt to climb, and back down slowly.
49
5. When descending a steep slope, always lower implements to the ground to reduce the risk of mower overturning.
49
Correct tyre pressure is essential for maximum traction. See 3.2 Specification.
49
WARNING
49
DO NOT USE ON SLOPES GREATER THAN 16°
49
WARNING
50
When the machine is being used, whether
50
cutting grass or not, on slopes, the ROPS
50
frame should be deployed and the seat belt
50
used. This rationale is based on the fact that
50
a seat belt must be worn with a ROPS to
50
comply with the Machiney Directive
50
2006/42/EC Sections 3.2.2, Seating & 3.4.3,
50
Rollover
50
Ransomes Jacobsen Limited recommends that
50
a local risk assessment is completed by the
50
owner/user of the machine to determine the risks
50
associated with working on slopes.
