SERVICE SECTION
SECTION 1: HYDROSTATIC SYSTEM
To change hydro oil on the Outlaw XP, remove oil
return lines from side of hydro tank and place them in a
disposable oil container. Start and run mower until oil level
is reduced down to about 2˝ of oil remaining in the tank.
Do not allow air to enter the oil lines in the bottom of the
tank. Keep in mind that only about 75% of the hydro oil
can be changed at a time. Use only 20w50 motor oil in the
hydro system. (Conventional or synthetic oil may be used)
Bad Boy recommends that the hydro oil and filters be
changed within the first 50 hours of usage and every 500
hours thereafter or once a year.
Change hydro oil filters by unscrewing them from the
filter head. Fill new filters with 20w50 motor oil before
installing. Use only Bad Boy replacement filters. Using any
other filter will result in damage to the hydro system and
void the warranty.
Once the system is refilled with oil, lift rear of mower until
tires are off the ground. Start engine, release parking
brake, stay clear of moving rear tires, loosen bypass bolt
½ to ¾ turns, move drive arms forward and backward 4 to
6 times slowly. This will purge the air from the system.
(the bypass bolt has a hole drilled through the side of the
bolt head). This valve also serves as a neutral for moving
the mower without the engine running.
