Service Refill Capacities
Note (1)
All non-road Tier 4 Final/Stage IV Technology diesel engines are required to use:
– Ultra Low Sulfur Diesel (ULSD) fuels containing 15 ppm (mg/kg) sulfur or less. Biodiesel blends up to B20 are acceptable when blended with 15 ppm (mg/kg) sulfur or less ULSD and when the biodiesel feedstock meets ASTM D7467 specifications.
– Cat DEO-ULS™ or oils that meet the Cat ECF-3, API CJ-4, and ACEA E9 specifications are required.
Sound Performance - Tier 4 Final/Stage IV: Suppression
Note (1)
The operator sound pressure level was measured according to the test procedures and conditions specified in ISO 6396:2008.
– The measurement was conducted at 70 percent of the maximum engine cooling fan speed.
Scoops
Type
Large capacity scoops for both wood chip and coal applications. A mesh screen integrated into the back of the scoop maintains visibility to the cutting edge. The chip scoop version has extra screens at the top due to higher capacity.
Components
Both scoops come with dual lift cylinders for increased lift capacity. Integrated stabilizer system makes sure that the scoop stays stable and centralized on the machine. Scoop tilt function is standard and provides ±15 degrees of tilt to maintain grade conditions and keep your operation safe.
