General Information Operator’s Manual The Operator’s Manual provides information regarding the operation, general maintenance and maintenance intervals for your Groundsmaster machine. Refer to that publication for additional information when servicing the machine. Towing Traction Unit IMPORTANT: If towing limits are exceeded, severe damage to the piston pump may occur. If it becomes necessary to tow (or push) the machine, tow (or push) in a forward direction only and at a speed below 3 mph. The piston (traction) pump is equipped with a by--pass valve that needs to be turned 90 o (one quarter turn) for towing. Refer to your Operator’s Manual for additional towing instructions. 1 Hydraulic System Figure 1 1. By -pass valve location Check Hydraulic Fluid The Groundsmaster 4000--D hydraulic system is designed to operate on anti--wear hydraulic fluid. The reservoir holds about 8 gallons (30.3 liters) of hydraulic fluid. Check level of hydraulic fluid daily. See Operator’s Manual for fluid level checking procedure and oil recommendations. 1 Figure 2 1. Hydraulic reservoir cap Groundsmaster 4000--D Page 4 - 3 Hydraulic System
