Pre-start Checks

Grasp the chain at the mid point of the guide bar and pull the
saw chain away from the bar rails. The drive link tangs should
nearly come out of the bar groove.
Fig. 43 – Check Saw Chain Tension
• Inspect for broken, cracked, damaged, or missing saw
chain components. Inspect loose rivets. If rivet can be
turned by hand, it is too loose.
• Inspect for excessive stretch. Stretch is actually wear
occurring to the flange of the rivet and the holes in drive
links.
• Inspect the chain chassis for abnormal wear patterns,
which are indicators of other cutting system issues with the
guide bar and drive sprocket.
Refer to the Oregon® Mechanical Timber
Handbook for additional information on the saw
chain and bar. A copy of this manual can be
found on the Wallenstein website under Technical
Reference.
6.7 Machine Break-In
Although there are no operational restrictions on the wood
processor when used for the first time, it is recommended that
the following mechanical items be checked:
For new saw chain, check tension often during the first 10
minutes of use.
Consider transporting new and newly sharpened saw chain to
and from the job site in a container with lubricant.
1. Lubricate your saw chain prior to use.
2. Increase saw speed gradually over the first 2–4 minutes
of running time while cycling the guide bar, until bar oil is
observed coming off the tip.
3. Check saw chain tension. Adjust if necessary.
After 1–5 hours of operation:
4. Check all nuts, bolts and other fasteners. Tighten to their
specified torque.
5. Check hydraulic system for leaks. Tighten all leaking fittings
and replace any leaking components.
6. Check machine fluid levels: Fuel, engine oil, and hydraulic
oil reservoir. Top up as required.
7. Check for entangled material. Remove all entangled material
before resuming work.
After 20 hours of operation:
8. Repeat Steps 4 through 7 listed above.
9. Check and adjust the tension on all drive chains. Chains
may stretch slightly as they wear in. See page 61.
10. Go to the normal servicing and maintenance schedule as
defined in the Maintenance Section. See page 52.
After 50 hours of operation:
• Re-tension Infeed Conveyor chain. See page 60
• Re-tension the Live Deck chain. See page 60.
• Re-tension the Integrated Conveyor chain (as equipped).
See page 62.
