Valves; Blade Repair - Alamo UNDER THE GUARDRAIL Operator's Manual

MAINTENANCE

VALVES

The major cause of valve malfunction is dirty oil or foreign material causing the valve spools to be scored or seals to
fail. If repairs are required remove the valve from the system and thoroughly clean all parts before reassembly.
Replacement parts and service kits are available. The valve body and spools are match fitted and are not
interchangeable or adjustable. Check the valve lever linkage for free movement to allow the detents to locate
without binding.

BLADE REPAIR

ALWAYS USE A SHARP KNIFE. A dull blade cuts poorly, may plug, and doesn't do a clean job. Replace Blade
if it becomes worn, bent, or damaged.
