(6) Clean cooling fan frequently.

(7) Keep hydraulic cylinder rods clean.

CAUTION

Once the SPEMS has been removed from the dusty, sandy environment, it must be thoroughly

cleaned. Dirt and dust will prevent the transfer of heat to the cooling air.

(8) Clean engine cooling fins (See TM5-2805-259-14).

(9) Change hydraulic system filters as needed, not according to operating hours.

g. Operation At High Altitude.

(1) Be aware that at high altitudes the SPEMS may operate more slowly because the engine has a

reduced air intake causing a corresponding reduction in available horsepower.

(2) The engine will be more likely to overheat at high altitudes. Be sure to idle for a sufficient time

(at least 15 minutes )to cool off, after a work period.

h. Operation In Snow or Mud.

(1) Keep the SPEMS clean and free of accumulations of snow or mud.

(2) Be sure cooling fan is clean and unobstructed.

(3) Be sure engine cooling fins are clean and unobstructed.
