12.1 Coolant level
Maintain coolant level. Low coolant level can cause
foaming and high blade temperatures. Replace
dirty coolant; dirty or weak coolant can clog the
pump, cause crooked cuts, a low cutting rate
and/or permanent blade damage. To fill the tank,
remove the filter cup and pour coolant into the hole
to about 80% of full capacity. Full capacity is 9
liters (2.5 gal). Follow coolant manufacturer’s
instructions for proper use and disposal.
12.2 Gear box
To change gear box oil:
1. Disconnect machine from power source.
2. Place bow in vertical position.
3. Remove drain plug (A, Figure 31) and drain oil.
(Follow local regulations for disposal of used
oil.)
Figure 31
4. Reinstall drain plug and return bow to
horizontal position.
5. Remove vent plug (B), and fill gear box
through the hole with approximately 0.3L
(10.14 oz.) of 90W oil.
6. Reinstall vent plug (B).
Completely drain and refill gear box oil after the
first 90 days of operation. Thereafter, change every
six months.
Periodically, after draining remove screws, cover
and gasket, and wipe out residual oil from gearbox
interior with a rag, before refilling. Also do this if
changing oil brands.
