Hydrostatic Transmission Fluid - Honda HS970 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.
It is normal for the fluid level no 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
reservoir before operation, but should rise into the reservoir when the
transmission warms up.
UPPER LEVEL
LOWER LEVEL
If the fluid level is low, add Honda Hydrostatic Fluid.
The use of other hydrostatic fluids will reduce transmission
performance and may damage the transmission. Use only Honda
Hydrostatic Fluid.
1.
Unscrew the reservoir cap and remove the seal. Be careful to
prevent dirt, water, or snow from entering the reservoir.
2.
Add Honda Hydrostatic Fluid 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.
