TW 160PH
OPERATING INSTRUCTIONS
10 / 51
C190-0013 11.04.2019
The no stress unit controls the feed rate of the material going into the chipping chamber. If the rotor speed is
below the predetermined level, the no stress unit will not allow the feed rollers to work in either forward or
reverse, until the rotor speed rises above the predetermined level. At this point, the feed rollers will start turning
without warning.
This label indicates the speed setting of the
chipper. With the throttle lever in the fast
position (hare) the machine is ready to chip.
When the machine is not in use for short
periods of time move the lever to the idle
position (tortoise) or turn off completely.

EMERGENCY STOPPING
There are two methods of stopping the TW 160PH chipper in the event of an emergency.
STOPPING THE ROLLERS
-Activating the red safety bar will stop the rollers immediately. To restart the rollers, just push the green forward
button or blue reverse button.
STOPPING THE ROLLERS & ENGINE
Pushing the red Emergency stop button positioned on top of the funnel kills all power to
both the engine and the rollers, bringing the machine to a complete stop. It overrides all
buttons and bars and will not allow the chipper to function until it has been reset. To
reset, pull out button until it returns to its original position, turn the ignition key back to
the off position, before restarting the machine.
BLADE WEAR
The most important part of using a wood chipper is keeping the cutter blades sharp. Timberwolf chipper
blades are hollow ground to an angle of 40 degrees. When performing daily blade checks ensure blade edge
is sharp and free from chips, if there is any evidence of damage, or the edge is “dull” change the blade(s). The
TW 160PH is fitted with 2 blades 109mm long. They are 100mm wide when new. A new blade should chip
for up to 25 hours before it requires sharpening. This figure will be drastically reduced by feeding the
machine with stony, sandy or muddy material.
As the blade becomes blunt, performance is reduced. With increased stress and load on the machine the
chips will become more irregular and stringy. At this point the blade should be sent to a reputable blade
sharpening company. The blade can be sharpened several times in its life. A wear mark indicates the safe
limit of blade wear. Replace when this line is exceeded.
The machine is also fitted with a static blade (anvil). It is important that the anvil is in good condition to allow
the cutting blades to function efficiently. Performance will be poor even with sharp cutter blades if the anvil
is worn.
The oil level will be visible through the tank wall. It should be within the upper
and lower level marks.
PETROL TANK INDICATOR
The fuel level may be inspected by removing the fuel filler cap and looking into
the tank.
