4.9 Controlling the Engine Speed
The TW 280FTR must always be run at full speed when
chipping.
Push and release the throttle selector switch to the fast
(hare) position and ensure the engine is running at full
speed before starting to chip (Figure 14).
If no chipping is to be carried out for more than a few
minutes, push and release the throttle selector switch back
to the slow (tortoise) position, to reduce stress on the
engine.

4.10 In-feed Safety Test
Before starting to chip, it is essential that the in-feed
safety circuit is confirmed to be working. Failure of the
in-feed safety circuit could prevent the in-feed rollers
from being stopped in an emergency, resulting in
serious injury or death.
1. Ensure the engine is running at full speed.
2. Lower the feed tray to the working position.
3. Press the red safety bar once to activate the control
system.
4. Press the GREEN Forward Feed Control (Figure 15).
• The in-feed rollers should turn forwards.
• The rollers should continue to turn after the
control is released.
5. Press the Red Safety Bar (Figure 16).
• The in-feed rollers should stop turning.
6. Press the BLUE Reverse Feed Control (Figure 17).
• The in-feed rollers should turn backwards while
the
BLUE feed control is held in.
• The rollers should stop turning when the control is
released.
7. Move to the opposite side of the feed funnel and
repeat steps 4 to 6, to confirm both sets of Feed
Controls operate correctly.
