Maintenance Procedures Every 8 Hours or Daily
Mast, Carriage, Header Hoses, and Lift
Chains, Inspect
WARNING
NEVER work under a raised carriage or forks.
Lower the carriage or use chains on the mast
weldments and carriage so they cannot move.
Make sure the moving parts are attached to a
part that does not move.
1.
Inspect welds on the mast and carriage for
cracks. Make sure the nuts and bolts are tight.
WARNING
Cleaning solvents can be flammable and toxic
and can cause skin irritation.
When using
cleaning solvents, always follow the recom-
mendations of the manufacturer.
When working on or near the mast, see Safety
Procedures When Working Near Mast.
Metal particles can fall into the eyes during the
operation of the mast. Failure to remove these
particles can cause eye injury. Remove metal
particles that are attached to the edges of mast
parts with a disc sander if necessary. Always
wear hearing protection, gloves, and eye pro-
tection when using a disc sander.
CAUTION
DO NOT use steam or high-pressure water to
clean the load rollers or the lift chains. Steam
and high-pressure water can remove the lu-
brication from the bearings in the load rollers.
Water in the bearings of the sheaves and the
link pins of chains can also shorten the service
life of these parts.
2.
Clean the mast assembly. Inspect the mast chan-
nels in the areas where the rollers travel. If there
are loose particles or metal particles that are at-
tached to the edges of mast parts, remove these
particles.
3.
Inspect the channel for excessive wear in the ar-
eas of roller contact. Check the rollers for wear
or damage.
4.
Inspect the load backrest extension for cracks
and damage.
5.
Inspect the lift chains for the correct lubrication.
Use engine oil or Hyster Chain and Cable Lu-
bricant (Hyster Part Number 171350) available
from your dealer for Hyster lift trucks.
6.
Visually inspect hoses/fittings for hydraulic
leaks; hose cover for cuts, cracks or exposed re-
inforcement; defective/broken clamping devices
or sheaves; proper tracking during operation.
Adjust/repair/replace hose/components as neces-
sary.
7.
Inspect the lift chains for cracks or broken links
and pins. See Figure 6.
8.
Inspect the chain anchors and pins for cracks and
damage.
9.
Make sure the lift chains are adjusted so they
have equal tension. If the chains need repair or
adjustment, it must be done by authorized per-
sonnel. See Figure 38.
