2.4 HYDRAULIC SAFETY
1.
Always place all tractor hydraulic controls in neutral
before disconnecting from tractor or working on the
hydraulic system.
2.
Keep all components in the hydraulic system in good,
clean condition.
3.
Relieve pressure before working on the hydraulic sys-
tem.
4.
Replace any worn, cut, abraded, flattened or crimped
hoses.
5.
Do not attempt any makeshift repairs to the hydraulic
fittings or hoses by using tape, clamps or cements.
The hydraulic system operates under extremely high-
pressure. Such repairs will fail suddenly and create a
hazardous and unsafe condi-
tion.
6.
Wear proper hand and eye pro-
tection when searching for a
high-pressure hydraulic leak.
Use a piece of wood or card-
board as a backstop instead of
hands to isolate and identify a
leak.
7.
If injured by a concentrated
high-pressure stream of hydrau-
lic fluid, seek medical attention
immediately. Serious infection
or toxic reaction can develop from hydraulic fluid pierc-
ing the skin surface.
8.
Before applying hydraulic pressure to the system,
tighten all components and check for damaged lines,
hoses, and couplings.

cording to original manufacturer’s specifications and
information in this manual.
8.

der a cap.
9.
Keep hydraulic hoses, electric cords, chains, and
other items from contacting the drive shafts.
10. Do not clean, lu-
bricate, or adjust the
drive shafts with the
