•
For deeper excavations or trenches, loosen the soil in layers of several inches.
Remove the soil with a shovel, backhoe, or vacuum. Repeat the procedure until the
desired depth is reached.
•
Excavation rates will vary depending
upon soil composition, soil compaction,
and the air delivered from the nozzle.
(See Table B.)
•
Use a portable (collapsible) barrier or
fence constructed from plywood or
canvas cloth, to keep dislodged soil
confined to the working area.
SHUT DOWN
•
Turn off the air compressor air supply valve.
•
Shut down the air compressor.
•
Securely hold the UTILITY AIRSPADE. Point the nozzle up and away from all
personnel and any loose objects, and depress the trigger. Continue to depress the
trigger until all compressed air from the tool and hose is fully expelled and the air
pressure gauge on the UTILITY AIRSPADE reads “0.”
•
It is now safe to disconnect the air supply hose. Store the UTILITY AIRSPADE.
MAINTENANCE
•
As with any professional-grade tool, the UTILITY AIRSPADE requires regular care to
ensure proper operation. Prior to each use, inspect the tool for any loose or visibly
damaged parts. Tighten or replace worn parts as required. Inspect the fiberglass
barrel for cracks, wear, or other damage. Remove dirt or other foreign material from
around the trigger and valve stem areas and from the fiberglass barrel. Periodically
apply light oil or lubricant (e.g. WD40) to ensure smooth operation.
