Engine Oil - Husqvarna HUV4421D Owner's Manual

BRAKE FLUID
Brake fluid level should be within 1/4-inch (6 mm) from the top of the reservoir (Figure 18). Also, brake fluid
should be clean with no residue in the bottom of the reservoir or other evidence of contamination.
ý
CAUT ION
• Use only DOT 5 (silicone) brake fluid. Use of any other type brake fluid is not recommended.

ENGINE OIL

Even though the low oil warning lamp on the instrument panel should illuminate if the oil level becomes low,
the engine oil level should be checked daily. The vehicle should be on a level surface when the oil is checked.
Do not overfill the engine with oil.
OIL PRESSURE – GASOLINE ENGINE
The gasoline engine has an oil filter that is mounted on a bracket next to the back side of the front panel. Inlet
and outlet oil-carrying hoses enable oil circulation to and from the engine. See following NOTE.
NOTE: The normal oil pressure value stated in the Honda engine manual is 28 psi at idle; however, the
remote filter design causes oil pressure to be 18 psi, which is normal for this type of oil circulation
design.
ENGINE OIL LEVEL CHECK
1. Remove the oil level dipstick from the oil filler tube and wipe oil from the dipstick. See Figure 19,
Figure 20, and Figure 21 on page 35. See following CAUTION.
ý
CAUT ION
• Do not remove dipstick while engine is running.
2. Check oil level by fully inserting the dipstick into the tube and immediately removing it.
3. If the oil level is at or below the low level mark on the dipstick gauge, add oil to the engine until the level
is between low and full levels (safe level). See following CAUTION.
CAUT ION
• Do not fill oil above the full level mark. Doing so will result in decreased engine performance
or damage to the engine.
