Using Your Terrasaw Tm : Some Useful Tips - terrasaw TS-400 Operator Owner's Manual

Using Your Terrasaw
CAUTION: UNDER NO CIRCUMSTANCES allow the digging chain to jam
or bog to a standstill whilst holding throttle on as this will cause severe
clutch damage. Refer also to powerhead manual.
1. Start the powerhead as per the manufacturers instruction manual. With a
firm grip on the powerhead handles and a firm footing, start cutting trench
with the Terrasaw blade at a comfortable angle (25 to 30 degrees from
vertical), and slowly walk backwards along your desired line. In lighter soil
types it may be necessary to do a final quick pass at the desired depth to
clean out any remaining spoil.
2. Most chainsaw engines are designed to operate best and develop
maximum power at near full throttle. The Terrasaw is designed for this and
also operates well at high throttle settings, recommended when digging in
difficult ground or at full depth. When trenching in confined or difficult areas
however, particularly at shallow depths of 200mm or less, the use of very
low throttle settings will provide extra safety and control.
3. When trenching freehand in particularly difficult soils the following technique
is useful. Place the Terrasaw's metal guard on the ground and use this as a
'pivot point'. Using a pushing down motion on the top handle and a pulling
up motion on the rear handle of the power head, allow the Terrasaw to
dig to the depth you require. Lift the Terrasaw up and back and repeat the
above. This method requires a quick final pass to even the bottom of the
trench!
4. If you strike solid obstacles such as rock, concrete, timber etc. remove
these before continuing. The Terrasaw is designed to dig earth, not large
stones or large tree roots!
5. For wider trenches, simply dig two parallel cuts to the desired width and
remove the remaining centre section by hand. If accurate trench placement
is important, consider marking your desired line with spray paint or similar.
6. Regular checking/adjustment of chains will extend chain life!
7. After digging, brush the loose dirt off of the digging chain, and inspect the
digging teeth for any damage. See Maintenance, Cleaning and Storage
