Service and oil change
1. Change the gear oil within the first 30 hours of extreme work, within 50 hours of moderate work or otherwise within the first 3 months.
2. After the first service, the gear oil must be changed every 300-500 hours
3. Check your gear box oil level every 10 hours of operation: Locate the level bung at the 2 o’clock position and make sure that the fill bung is centred and the trencher level. Top up your gear oil through the fill bung until the oil can be seen exiting the level oil
4. Carry out a full service every 12 months by a trained and authorised Digga technician
Pre-operational checks
1. Visually inspect your trencher and components
2. Check that all nuts and bolts are in place and properly tightened
3. Check all fittings and hydraulic hoses are tightened and secure
4. Check that safety stickers are in plain sight and legible
5. Check externally for any oil leakage around hoses, fitting, motor and gearbox.
6. Check any war and tear on linkages and pins, chains and teeth
Adjust your trenching depth
Loosen and remove two 28mm mounting nuts and washes
Once unbolted, you can remove the skid plate and rotate until the mounting the holes line up with bolts again at your desired depth setting (refer to your operator’s manual for depth charts and further information
Refit washes and nuts and tighten.
Adjust your trencher chain
1. Remove the 14mm bolts holding the adjustments spanner to the trencher boom
2. Use the adjustment spanner to turn and adjust the nut clockwise for loosening or anti-clockwise for tightening
3. To achieve the correct chain tension, check the adjustment at mid-way point of your chain. Allow for 20-30mm of vertical movement between chain and boom.
