3. Fully insert the dipstick then remove it again.
4. Determine if engine oil is low. Oil should be between
the upper and lower marks (Figure 15) on the dipstick.
5. If the oil is below the lower mark on the dipstick, remove
the oil filler cap (Figure 15) and add engine oil up to
the upper mark on the dipstick. Refer to Table 6 for
recommended oil viscosity.
CAUTION
NEVER overfill the oil pan. ALWAYS allow time for
any added oil to make its way to the oil pan before
rechecking the level.

NOTICE
Use 4-stroke motor oil that meets or exceeds the
requirements for API service category SJ or later
(or equivalent).
6. When replacing the dipstick, make sure it is fully
inserted into its holder to keep the crankcase sealed.
7. Repeat steps 2–6 on the remaining engine.
HYDRAULIC OIL
1. Make sure the trowel is secured on a level surface with
the engines stopped.
2. Visually inspect the level of hydraulic oil in the
hydraulic oil reservoir (Figure 17). Hydraulic oil
should be visible between the MIN and MAX lines on
the reservoir.
CAUTION
Hydraulic oil can get HOT!
ALWAYS allow hydraulic oil to cool before
removing the fill cap. NEVER remove
the fill cap when the oil is hot or spillage
will occur. ALWAYS clean up any spilled
hydraulic oil immediately.

3. If the hydraulic oil level is low, remove the hydraulic
oil filler cap (Figure 16), and add hydraulic oil up to a
level midway between the MIN and MAX lines on the
reservoir. DO NOT overfill. Use only Parker DuraClean
ISO 46 hydraulic oil or equivalent. Replace the filler
cap when finished.
