Drive Belt Replacement; To Replace Or Clean Check Valve - Industrial Air IH1393075 Manual Del Operador

To check pulley alignment, remove the belt guard and place a
straightedge (see A) against the pump flywheel (see B) (See Fig.
9). Measure and record the distance from the straightedge to the
edge of the drive belt at point C. Then measure the distance from
the straightedge to the edge of the drive belt again at points D and
E. Both distances should be the same as at point C. If D or E are
different from C, there is a misalignment which must be corrected
before the compressor is run. To correct a pulley misalignment,
use the following procedure.
1. Remove the front of the belt guard by removing the screws
and washers using a Torx T25 bit.
2. Loosen the engine mounting bolts.
3. Remove the 2 screws and lock washers from the hub using a
7/16" wrench.
4. Insert the screws into the threaded holes on the hub and
tighten to pull hub away from sheave, remove screws.
5. Align the engine pulley with the pump flywheel (C-D-E must
be equal ).
6. Replace hub by aligning non-threaded holes in hub to holes
in sheave. Insert screws and lock washers and tighten.
7. Adjust the proper belt tension.
8. Retighten the engine mounting bolts to 130-180 in.-lbs.
9. Reinstall the belt guard. All moving parts must be guarded.

DRIVE BELT REPLACEMENT

WARNING:
To avoid personal injury, always
shut off the gasoline engine and relieve all air
pressure from the system before performing any
service on the air compressor. Do not use the unit
with the shrouds or belt guard removed. Serious
injury could occur from contact with moving parts.
1. Remove the front of the belt guard by removing the screws
and washers using a Torx T25 bit.
2. Loosen the engine mounting bolts.

3. Shift the engine towards the pump to the point where the
belts can be easily removed and installed.
4. Remove and replace belts. NOTE: The belts must be
centered over the grooves on the flywheel and motor pulley.
5. Shift the engine back to the point where the correct deflection
exists (see "Drive Belt Tension Adjustment").
6. Retighten the engine mounting bolts to 130-180 in.-lbs.
7. Check to ensure that the tension remained correct.
8. Reinstall the belt guard. All moving parts must be guarded.

TO REPLACE OR CLEAN CHECK VALVE

WARNING:
shut off the gasoline engine and relieve all air
pressure from the system before performing any
service on the air compressor. Do not use the unit
with the shrouds or belt guard removed. Serious
injury could occur from contact with moving parts.
1. Shut OFF the gas engine. Relieve all the air pressure from
the tank (refer to "Shutdown" in Operating Instructions).
Make sure the compressor has cooled down before
servicing.
2. Using the appropriately
Fig. 9
sized wrench, loosen the
compression nuts (A) on
the check valve (B) and
pump head (C). Remove
Engine
the transfer tube (D).
3. Using the appropriately
sized wrench, loosen the
compression nut (F)
from the connector (G),
located on the side of
the check valve.
Remove the bleeder
tube (E).
4. Making note of the
orientation for
reassembly, unscrew the
check valve from the
tank (counterclockwise)
using the appropriately sized wrench.
5. Using a pencil or screwdriver, carefully
push the valve disc up and down. If the
valve disc does not move freely up and
down, the check valve needs to be
cleaned or replaced.
6. Clean the check valve with warm soapy
water and make sure to dry thoroughly
before reinstalling. If the disc valve still
does not move freely up and down, it will
need to be replaced.
7. Apply thread sealant to the check valve
threads and reinstall into the tank by
turning clockwise. Make sure it is the
same orientation as when it was
removed.
8. Replace the bleeder tube and tighten compression nut.
9. Replace the transfer tube and tighten compression nuts.
10. Perform the "Break-in of the pump" procedure in the
Operating Instructions to make sure there are no leaks and
the check valve is working properly.
