Select the 7E in. diameter long compressor attach-
ment and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC and insert an air adaptor
into th€ spark plug hole. Pump air into the cylinder
to keep the valv€ closed while cgmpressing springs
and removing the valve keepers.
Position the lever arm under the cross shaft so the
lever is psrpendicular to the shEft and ths compres-
sor attachment rests on toD of the rstainer for th€
spring being compressed. Use the rear position slot
on the lever as shown.
NOTE: Put shop towels over the oil passag€s to
prevent the valve keepers from falling into the cylin-
der h€ad.
