Filter Cleaning; Cleaning And Lubrication - Bostitch GF9033-E Safety & Operating Instructions Manual

FILTER CLEANING

When working on the tools, do not lose any parts of
the disassembled tool and use only genuine BOSTITCH
parts to ensure proper tool operation and safety.
1. Before cleaning, check that the tool has cooled down
completely, and then remove all nails, the fuel cell
and the battery from the tool (Fig. 21).
2. Remove the filter cover using a flat screwdriver (Fig.
22) and remove the filter (Fig. 23).
3. Remove the dust and rubbish from the filter with
cleaner. Ensure that the filter is dry and free from
contamination (Fig. 24). Replace the filter and filter
cover. If the filter is damaged, replace the filter with
a new one.
4. Always carry out 5-10 test cycles of the tool on waste
material before using on a finished surface to expel
any cleaning material residue.
CLEANING & LUBRICATION
Make sure that you have read and understood all safety
warnings and cleaning procedures before attempting to
operate or clean this tool. Failure to do so may result in
serious injury.
WARNING: Make sure that the 4 hex socket head bolts
are securely attached to the cylinder head before
operating the tool. Loose or missing bolts may cause
leakage of burning gases causing injury to the user and
damage to the tool and property.
1. Before cleaning, check that the tool has cooled down
completely, and then remove all nails, the fuel cell
and the battery from the tool (Fig. 21).
2. Using a 4mm hex key, remove and retain the hex
socket head bolts (Fig. 25).
3. Remove the top cover (Fig. 26).
4. Disconnect the motor lead (Fig. 27) and unplug the
spark plug connection from the spark plug (Fig. 28).
5. Gently lift the cylinder head away from the
combustion chamber (Fig. 29).
6. Ensuring you do not damage the fan blades, carefully
remove the o-ring from the fan (Fig. 30).
7. Using a dry cloth, clean and remove all deposits
from the o-ring. Inspect the O-ring for damage and
if necessary, replace it (Fig. 31).
8. Clean the cylinder head using brake cleaner, paying
particular attention to the spark plug (Fig. 32). A small
brush may be useful to help release some debris. You
may need to repeat this 2 or 3 times until clean.
9. Replace the o-ring on to the cylinder head. Lubricate
the o-ring using BOSTITCH gas nailer lubricant (Fig.
33).
10. Spray brake cleaner into the cylinder to loosen
any residue.
11. Using a blunt instrument (e.g. a screwdriver handle),
push down the piston (Fig. 34).
12. Spray brake cleaner into the combustion chamber
and the chamber head. You may need to do this 2 or 3
times using a small brush to loosen some of the more
stubborn residue (Fig. 35). Wipe clean any remaining
residue (Fig. 36)
13. Using a screwdriver or similar implement, push the
driver blade back into the tool (Fig. 37).
14. Ensuring the O-ring is evenly seated on the cylinder
head (Fig. 38), carefully locate the cylinder head back
on top of the tool, taking care not to damage the fan
blade (Fig. 39).
15. Pull back the nail feeder to disengage the tool
lockout and press down the contact arm on a hard
surface (Fig. 40).
16. Reconnect the motor lead wire and then the spark
plug lead wire (Fig. 41).
17. Replace the top cover, ensuring that none of the
leads are trapped and replace the socket head bolts
(Fig. 42).
18. Replace the filter assembly (Fig. 43).
19. Test the tool by pulling back the nail feeder to
disengage the tool lockout and pressing down the
contact arm on a hard surface. The fan should
operate (Fig. 44).
NOTE: Always carry out 5-10 test cycles of the tool on
waste material before using on a finished surface to
expel any cleaning material residue.
