Tension And Compression In Timber; Service - Anova MG3800 Manual De Uso Y Mantenimiento

BUCKING
Bucking is the sawing of a log or fallen tree into smaller
pieces.
1. Keep both hands on the handles at all times.
2. Support logs if possible.
3. When cutting on a slope or hillside, always stand uphill.

TENSION AND COMPRESSION IN TIMBER

A length of timber lying on the ground will be subject to
tension and compression depending at which points the
major support is.
When timber is supported at its ends the compression
side is at the top and the tension side is at the bottom.
To cut between these support points make the first cut
downwards approximately 1/3rd the timber diameter.
The second cut is made upwards and should meet the
first cut.
When the timber is supported at one end only make the
first cut upwards approximately 1/3rd the timber diameter.
The second cut is made downwards and should meet the
first cut.
WARNING
ALL CHAIN SAW SERVICE, OTHER
THAN ITEMS LISTED IN THE
OPERATOR'S MANUAL SHOULD
BE PERFORMED BY COMPETENT
SERVICE PERSONNEL.
Operation and maintenance
If you have misjudged the effects of tension and
compression, and cut from the wrong side, the timber
will pinch the guide bar and chain and trap in it.
Racing the engine with the chain jammed will burn
out your clutch.
If the chain should become jammed and the saw
can not be removed from the cut do not force it out.
Stop the saw, force a wedge into the cut to open it
up.
Never force the saw when it is jammed. Do not force
the saw into the cut. A dull chain is unsafe and will
1.
cause excessive wear to the cutting attachments.
A good way to telt when the chain is dull is when
fine saw dust comes out instead of chips.
Do not touch hot surfaces of cylinder cover and
silencer, after you used the chain saw.
NEVER USE THROTTLE LATCH
