5.8 Controlling the Engine Speed
The TW 230HB must always be run at full speed when
chipping.
Move the throttle lever all the way to the fast (hare) position
and ensure the engine is running at full speed before
starting to chip (Figure 12).
If no chipping is to be carried out for more than a few
minutes, move the throttle lever back to the slow (tortoise)
position, to reduce stress on the engine.

5.9 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 13).
• 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 14).
• The in-feed rollers should stop turning.
6. Press the BLUE Reverse Feed Control (Figure 15).
• 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.
