MiniTrencher GeoRipper GR16, Инструкция по эксплуатации и безопасности

Страница: 12 / 20

SPECIAL SITUATIONS
1. The GeoRipper® minitrencher is not designed to trench in solid rock.
2. For digging in light or sandy soils containing fine, hard stones, GeoRipper® minitrenchers
should be at full speed prior to contact the ground. When trenching is complete, lift the
digging bar and chain clear of the trench prior to throttling down. This will greatly reduce
the occurrence of rock jambs. Decreasing tension on the chain will also improve trenching
in these conditions.
3. When digging at full depth in difficult, wet, pliable clays, it is recommended to make two
half-depth passes in opposite directions. This will reduce operator fatigue, reduce engine
strain, and reduce the possibility of jamming the digging chain with mud.
4. When cutting curves or radiuses, it is advisable to use several shallow passes rather than a
single, full-depth cut.
5. When trenching across a roadway, it is recommended to first loosen the compacted
gravel/stones along the desired line. Removing larger rocks before trenching will also
increase productivity and avoid damaging the digging chain.
6. If digging chain is slowing or stopping because of excessive soil buildup, periodically stop
the machine and clear the material for the chain, sprockets and discharge chute. Some
soils will buildup on the sprocket and add tension to the chain. Loosening chain can help.
Keeping engine speed high and constant can also help.
MAINTENANCE, CLEANING & STORAGE
IMPORTANT! Inspect powerhead air filter daily. Clean or replace when necessary as per
powerhead Operator’s Manual.
Blow out and clean cooling find on powerhead with low-pressure, compressed air every 8-10
hours of operation. Clean out any embedded or sticky debris.
Check drive belt tension and inspect drive belts for cracking or other wear daily. Replace belt as
need. Check your orange tool pouch for an extra drive belt.
Replace anti-vibration mounts and other wearable powerhead components as required to
maintain the powerhead.
4-Cycle Engines: Change oil for the first time after 20 hours of use. After initial oil change, oil
shall be changed every 30-40 hours of operation.
To replace Nose Sprocket and Nose Assembly Plates
Heat screws to 500 degrees F (260 degrees C) to breakdown locking compound. An
impact driver with a 5mm hex bit will help to loosen screws. Add a stud locking compound (Red
Loctite) to screws before reinstalling. Tighten Nose bolts to 18 foot-lb torque.
When storing the GeoRipper® minitrencher, drain fuel from tank, run machine dry, and oil
digging chain. Follow storage instructions in powerhead Owner’s Manual.
