MAINTENANCE INSTRUCTIONS
1. CLEAN HYDRAULIC OIL IS ESSENTIAL! 80% of all hydraulic component failures are caused by con-
tamination of the hydraulic oil. Always keep all dirt and other contaminates from entering hydraulic sys-
tem during disconnect and connect operations. Always use dust caps and plugs on all quick disconnects
when not in use. Tightly cap all hydraulic openings to hold oil in and keep dirt and other contaminates
from entering hydraulic systems.
2. CHECK ALL HYDRAULIC OIL DAILY FOR CONTAMINATION. If contamination is present, determine
the source of the problem.
3. INSPECT ALL HYDRAULIC HOSE ASSEMBLIES DAILY for cracked and brittle covers caused by
excessive heat. Reduced viscosity of hydraulic oil occurs at higher operating temperatures and causes
a breakdown of fluid additives such as wear inhibitors. Excessive heat will cause higher internal leak-
age in drive unit motor to become brittle and crack. Replacement of hoses before failure will prevent
loss of hydraulic oil, time consuming “bleeding” of system, hydraulic oil contamination, and component
damage caused by cavitations. It will also reduce the chance of personal injury caused by hydraulic fluid.
4. CHECK AUGER DAILY for loose, worn or broken cutting teeth and point. Worn teeth or point can dras-
tically affect auger penetration and greatly reduce auger life expectancy. Always keep spare teeth and
points on hand. Some digging conditions may require checking teeth and point at more frequent inter-
vals.
5. CHECK DRIVE UNIT AND ALL ACCESSORIES DAILY for loose, bent, cracked, or worn, bolts and fas-
teners. Always use grade 5 or better replacement bolts. Always use lock washers with standard hex
nuts or self locking nuts.
6. CHECK ALL CONNECTING PINS DAILY for bends, cracks, breaks, or wear. Replace if any of these
conditions exist.
7. CHECK DRIVE UNIT OUTPUT SHAFT DAILY for bends, cracks, breaks, or wear. Replace if any of
these conditions exist.
8. CHANGE PLANETARY GEAR REDUCTION OIL AFTER FIRST 50 HOURS OF OPERATION, THEN
EVERY 1000 HOURS OR IN ONE YEAR, WHICHEVER COMES FIRST. Use mild extreme pressure
lubricant API-GL-5 number 80 or 90 for filling planetary gear reduction under normal temperature ranges
between 0 degrees and 120 degrees. Approximate oil capacity for models EA10, EA15PD, and EA19 is
two pints. Check oil level daily to assure proper lubrication is maintained.
9. When storing Drive Unit for any length of time be sure Drive Unit motor and hoses are full of clean oil.
Also, be sure that Planetary Gear Reduction is full to the recommended capacity for each model as out-
lined in number 8 above.
10. Drive Unit output shaft, inside of Auger Collar, Variable Auger Extension shaft, inside of Variable Auger
Extension Collar and all Connecting Pins should be coated liberally with grease as required to prevent
rust and reduce wear.
11. Once paint has been worn off auger, coat liberally with grease as required, to prevent rusting.
12. Check Planetary Gear oil as follows. Lie Drive Unit horizontal with ground, place bottom drain plug
straight up. Remove plug, tilt drive unit at 2:00 or 10:00. Fill until oil leaks out from hole at one of these
positions.
