Then repeated under normal operating conditions. The following procedures are best performed with the vehicle drive wheels off the ground. Air creates inefficiency because its compression and expansion rate is higher than that of the oil approved for use in hydrostatic drive systems. PURGING PROCEDURES Due to the effects air has on efficiency in hydrostatic drive applications, it is critical that it is purged from the system. Apply the bypass valve for each transaxle and lock the vehicle parking brake. The following procedure can be performed with the transaxles installed in the vehicle, and the vehicle on level ground. To ensure constant fluid quality levels and longer life, an initial oil and filter change at 75-100 hours, then every 400 hours thereafter is recommended. 3.ДЇLUID CHANGE PROCEDURE This transaxle is designed with an external filter for ease of maintenance. NOTE: Always replace the filter when performing any internal maintenance to the transaxle. When tightening the fasteners, refer to the table on page 21 for the required torque values. Reassemble all parts in the reverse order of disassembly. Remove the hex head screws (105), and filter guard (106). Insure that no belt slippage can occur.ДЇILTER AND FILTER GUARD Refer to Figure 4 Disassembly Assembly 1. Inspect the vehicle drive belt, idler pulley(s), and idler spring(s). Check oil level in accordance with вЂњFluid Change Procedure,вЂќ step 12.

Insure that the current application does not exceed load rating.
