INSPECTING AND ADJUSTING THE
TRACK TENSION
• If you must work beneath the raised
machine or working equipment, always
use wood blocks, jack-stands or other
rigid and stable supports. Never get
under the machine or working
equipment if they are not sufficiently
supported. This procedure is especially
important when working on hydraulic
cylinders.
• Be careful with the high-pressure grease
In the track adjuster, the grease has
been injected under high pressure. If the
tension is adjusted without following the
prescribed procedure, the grease
discharge valve may fly off, resulting in
injury.
· Loosen the grease discharge valve
slowly. Do not turn it more than one
turn.
· Do not put your face, arms, legs or
body in front of the grease discharge
valve.
· If grease does not come out when the
grease discharge valve is loosened,
the valve is faulty. Ask a Takeuchi
service agent for repair.

EVERY 50 HOURS
<TL12>
Increasing the tension
1. Remove the cover (1).
2. Inject grease through the grease fitting of
the grease discharge valve (2) with a
grease gun.
3. Inspect the track tension.
1. Lower the lift arms and tilt the bucket
forward to raise the front of the machine
off the ground as far as it will go.
2. Measure the clearance between the center
track roller tread and the surface of the
track where it makes contact with the
roller.
<TL8>
The clearance (A) should be 25 to 50 mm
(1.0 to 2.0 in.).
<TL10/TL12>
The clearance (A) should be 15 to 30 mm
(0.6 to 1.2 in.).
