WARNING!

5.Logs under strain require special attention to prevent the saw from pinching. The first cut is made on the compression side to relieve the stress on the log (see fig. 33,34).The bucking cut is then made as shown. If the saw pinches, stop the engine and remove it from the log.

WARNING!

6.Onlyproperlytrainedprofessionalsshouldwork in an area where the logs, limbs and roots are tangled (i. e. a blowdown area, fig. 35). Work- ing in blowdown areas is extremely hazard- ous.

WARNING!

7.Drag the logs into a clear area before cutting. Pull out exposed and cleared logs first.

Maintaining and storing the saw

Keepthe chain, bar and sprocket clean and lubricated; replace worn sprockets or chains.

Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut and burn marks appear on the wood.

Keep the chain at proper tension. Tighten all nuts, bolts and..screws except the carburetor adjustment screws after each use.

Keep spark plug and wire connection tight and clean.

Store saws in a high or locked place, away from children.
