Hydrostatic Transmission Fluid - Honda HS624 Owner's Manual

Hydrostatic transmission fluid
Check the hydrostatic fluid level in the reservoir.
Hydrostatic fluid expands and contracts with changes in temperature. The
UPPER and LOWER level marks on the reservoir are calibrated for room
temperature fluid.
lt is normal for the fluid level to rise above the UPPER level mark when
snowblower operation warms the transmission.
When checking the level of cold fluid, below room temperature, refer to
the temperature chart for appropriate fluid levels.
At temperatures below
-2OOC (--4OF), fluid may not be visible in the
reservoir before operation, but should rise into the reservoir when the
transmission warms up.

1 .Unscrew the reservoir cap and remove the seal. Be careful to prevent
dirt, water, or snow from entering the reservoir.
2.Add HONDA HYDROSTATICFLUID to bring the fluid level to the UPPER
level mark at room temperature, or to the appropriate level shown in the
temperature chart. Do not overfill.
3.Reinstall the seal, and tighten the cap securely.
