OPERATING INSTRUCTIONS
The engine management unit controls the feed rate of the material going into the chipping chamber. If
the engine speed is below the predetermined level, the engine management unit will not allow the feed
rollers to work in the forward “infeed” direction, until the rotor speed rises above the predetermined
level. At this point the feed rollers will start turning without warning. The reverse function will operate
at any engine speed.
LOCATE the machine on firm level ground.
CHECK machine is well supported and cannot move.
CHECK all guards are fitted and secure.
CHECK the discharge unit is in place and fastened securely.
CHECK discharge tube is pointing in a safe direction.
CHECK the feed funnel to ensure no objects are inside.
CHECK feed tray is in up position - to prevent people reaching rollers.
CHECK controls as described below.
CHECK (visually) for fluid leaks.
CHECK fuel and hydraulic oil levels.
For parts location see diagrams on pages 3 & 4.
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 190TVGTR is fitted with 2 blades 127mm (5") long. They are 100 mm
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 on the
reverse side 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.
AUTO CONTROLS
EMERGENCY STOPPING
DAILY CHECKS BEFORE STARTING
There are two ways of stopping the TW 190TVGTR 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 ENGINE
Should the entire machine need to be stopped in an emergency the red button on top of the engine
guard should be pushed. This will shut down the engine in the shortest possible time. The engine
cannot be restarted until the button is pulled out again to reset it.
