STEP 4: ATTACHING THE HANDI-GUN
1. Apply petroleum
jelly to the face
of the gun, insert
bottom tab of nozzle
into bottom slot
of dispensing unit.
STEP 4.1: ATTACHING THE HANDI-GUN II
1. Apply petroleum
jelly to the face of
the gun.

STEP 5: NOZZLE CARE

• Once the trigger is released, it must be reactivated within 30 seconds or a new nozzle must be installed.
Failure to do this could result in chemical leakage, spills, splashes or clogs which can ruin the dispensing
unit and/or hoses.
• Always make sure the Handi-Gun
before attaching a new nozzle. This makes removal of nozzles easier and protects the face of the gun hose assembly.
• If foam has not cured, Handi-Cleaner
• Cleaning the nozzles more than twice is not recommended.

STEP 6: TACK-FREE TEST

Tack-free time refers to the time elapsed between when the product is dispensed and when the foam expands
and cures initially, so that it is no longer tacky to the touch. Tack-free time is an important property that can
be used frequently before and during a job to obtain an indication that the product is being dispensed to the
proper A/B ratio.
1.
Spray test shot.
2. Start timer as soon as you stop spraying.
3. Take a stick and gently touch the top of the foam. Each time you touch the
foam; do so at a different point on the stick.
4. Watch for the foam to stop adhering to the stick.
5. As soon as the foam is no longer tacky, stop the timer.
6. Check the timer for the tack-free time.
7.
Refer to the Technical Data Sheet (TDS) to find the proper tack-free time
for the system being used.
8. For best results, perform a ratio test (see step 3).
9. With the nozzle removed, check that both chemicals flow with equivalent force.
10. Partial or complete blockage of one chemical port will result in off-ratio foam.

STEP 7: APPLYING FOAM

1. For optimum results, the Magnum Heated System
Therefore, the recommended chemical temperature when using the Magnum Heated System is 70-85°F
(21-29°C), see TDS for product specific process (core) chemical temperature recommendations.
2. Condition cylinders at ambient conditions to bring chemical that is too warm or too cold to optimal chemi-
cal temperature for several days (see figure 1 on page 3).
3. Release the trigger safety. When pulling the trigger for the first time, it is recommended to trigger the gun
only 1/2 to 3/4 open until the desired output and spray pattern is achieved.
4. Conduct ratio shots (see step 3) before initial daily spray and every two hours during the job. Maintain
accurate records utilizing Daily Spray Log worksheet – key to troubleshooting and tech service.
5. Perform tack-free test (see step 6).
6. Once the trigger is released, it must be reactivated within 30 seconds or a new nozzle must be installed.
7. Failure to do this could result in chemical leakage, spills, splashes or clogs which can ruin the dispensing
unit and/or hoses.
Important: After releasing the trigger of the Handi-Gun
accidental discharge. After releasing the Handi-Gun II
engages to prevent accidental discharge.
