tures. Refer to the lubrication instructions in Chapter 3 for recommended viscosity’s.
(2)
Check oil levels frequently and add oil as required to maintain proper levels.
c. Sandy or Dusty Conditions.
(1)
Lubricate equipment frequently and watch fluid levels closely.
(2)
Change hydraulic oil two or three times more frequently.
(3)
Use liberal amounts of grease when lubricating pressure grease points to force out any contaminated
grease.
(4)
Keep equipment as clean as possible at all times.
d. High Humidity and/or Salt Water Conditions.
(1)
Protect cylinder shafts and painted or polished surfaces by keeping them well lubricated or coated with a
thin layer of grease or similar preservative.
(2)
Remove rust and corrosion as they appear and repaint affected surfaces.
(3)
Keep pressure grease fittings well lubricated to prevent entry of moisture.

a.
Cold Weather Operation.
(1)
Cold weather can cause clogged fuel lines and filters. Paraffin oil should be mixed with the diesel fuel
in the following proportions, according to the temperature:
Temperature Fuel Content
32 to 5 deg F
(0 to -15 deg C)
100%° diesel fuel
4 to -4 deg F
(-16 to -20 deg C)
75% diesel, 25%° paraffin
-5 to -25 deg F
(-21 to -32 deg C)
50% diesel, 50%° paraffin
(2)
Condensation in the fuel tank can affect the fuel flow to the engine. Keep tank as full as possible
during cold weather. Refill fuel tank more often than normal. If fuel tank becomes contaminated with
water, drain and flush tank and refill with new fuel.
(3)
Change engine oils and lubricate equipment with lubricants recommended for cold weather operation.
Refer to lubrication instructions in Chapter 3.
b. Hot Weather Operation.
(1)
Use lubricants that are more viscous and resist breakdown at high tempera-
