MAINTENANCE
Blades
Check the Blades for cracks and wear and Blade Bolts for tightness, daily. Blades should be replaced when
they are worn excessively, bent, deformed, or out of balance.
Blades should always be replaced in pairs. Blades of different weights can cause serious
imbalance and damage to the machine and personnel. When replacing blades, take care to
replace the blade bolts, nuts, and washers.
Hardware
Most nuts and bolts will stay tight and therefore need only periodic checking. However, the following nuts and
bolts are extremely important and should receive special attention:
Spindle Housing Bolts:Tighten to 400 Ft./Lbs. Torque
Blade Bolts:Tighten to 400 Ft./Lbs. Torque
Blade Bar To Spindle Bolts:Tighten to 400 Ft./Lbs. Torque
Be certain to clamp or securely support the Spindle Housing and subassemblies to prevent
injuries to hands and feet due to inadvertent dropping or falling over.
Always wear safety glasses and gloves to prevent eye and hand injury when chiseling or
hammering on metal components. Hardened metal will chip unexpectedly.
An assembled spindle housing is quite heavy. Use a hoist or get help to handle them safely.
Lift carefully and properly using your legs to lift - NOT YOUR BACK.
Cylinder Rod Maintenance
It is important to visually inspect the hydraulic cylinder rods daily before use. It is highly recommended that
while the machine is stored or getting very little use that a protectant is applied to the hydraulic cylinder rods to
prevent degradation. If the machine receives more frequent use, be sure to fully cycle each cylinder function so
that the cylinder rod is coated by the systems hydraulic fluid. Depending on your operating environment it may
be necessary, under normal operating conditions, to apply a protective lubricant to the cylinder rods for protec-
tion against rust and pitting. Hydraulic fluid may provide a suitable amount of protection, but remember any
protectant can attract dust and debris so attention must be given to the cylinder rods daily. Also remember that
any other protectant must be compatible with hydraulic fluid. Alamo Industrial is not responsible for rust or pit-
ting of the cylinder rod due to weather exposure or impacts from normal operation or mounting. If hydraulic cyl-
inders and or the cylinder rods are damaged as a result of the rods rusting or pitting, the hydraulic cylinders
and rods will not be covered under warranty by Alamo Industrial.
