•
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
AIR-SPADE nozzle.
(See Table)
•
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 AIR-SPADE. 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 AIR-SPADE reads “0”.
•
It is now safe to disconnect the air supply hose. Store the AIR-SPADE as desired.
MAINTENANCE
•
As with any professional grade tool, the AIR-SPADE 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. Brush off dirt or other foreign
material from around the trigger and valve stem areas. Periodically apply light oil or
lubricant (e.g. WD40) to the exposed valve stem to ensure smooth operation.
