Scag Power Equipment SWZV Manuel D’Utilisation

The hydraulic oil should be changed after every 500 hours
or annually, whichever occurs first.  The oil should also
be changed if the color of the fluid has become black or
milky.  A black color and/or a rancid odor usually
indicates possible overheating of the oil, and a milky color
usually indicates water in the hydraulic oil.

1. Park the mower on a level surface, stop the engine

and remove the ignition key.

2. Place a suitable container under the hydraulic oil

filter.  Remove the fill cap from the reservoir.
Remove the drain plug from the fitting on the
reservoir base. (See Figure 7-2).  Allow the fluid to
drain into the container and properly discard it.

3. Re-install the drain plug into the reservoir and be sure

it is tight.

4. Fill the reservoir to full tab below the filler neck with

20W50 motor oil.

5. Replace the reservoir fill cap.  Start the engine and

drive forward and backward for two minutes.  Check
the oil level in the reservoir.  If necessary, add oil to
the reservoir.

The hydraulic oil level should be checked after the first 10
hours of operation. Thereafter, check the oil after every
200 hours of machine operation or monthly, whichever
occurs first.

1. Wipe dirt and contaminants from around the reservoir

cap.  Remove the cap from the hydraulic oil reservoir.

2. Visually check the level of hydraulic oil.  Hydraulic oil

must be at the full tab below the filler neck.  If the
fluid is low, add 20W50 motor oil.  DO NOT overfill;
(overfilling the oil reservoir may cause oil seepage).

3. Clean the fill cap and install it onto the reservoir.
