Coolant Pump Honing Oil
The coolant pump is located in the back of the splash tank. The coolant drains under the block xture into
a sump under the machine.
Every 8 hours, change the lter paper. Change the honing coolant when it gets dirty. When changing
coolant, completely clean tank and lter screen. Use approximately 4 gallons of Rottler synthetic
honing coolant mixed with 80 gallons of water. Use a Refractometer to achieve a more accurate
mixture.
Hydraulic System
This system is used to regulate the stroking speed.
Every 175 hours, check the hydraulic liquid level in the back of the carriage under the Rocker Arm. If
hydraulic oil is needed add specied oil to the top of the reservoir. Remove breather to ll. Fill to
mark on reservoir.
Use Mobil DTE EXCEL 46, or equivalent ISO VG 46 hydraulic oil.
