6 DO-IT-YOURSELF MAINTENANCE
16
!WARNING:
It is recommended that the engine be cool or cold when changing the spark plugs. If the engine is hot,you could burn yourself on the in- sulated connector, the spark plug or the engine itself. G060C03A
6. To install the new spark plug, guide
the socket down over the sparkplug, being careful not to damage the ceramic insulator.
NOTE: Spark plugs should be tightened firmly. Over-tightening can damagethe threads in the aluminum cylin- der head. Also, leaving them too loose can cause the spark plug toget very hot and possibly result in damage to the engine.
7. Replace the cable by pushing the insulated connector directly down onto the electrode. Check to be sure it has snapped into place and can'tfall off.

G060C01S-GAT Changing the Spark Plugs You will find it easier to change spark plugs if the engine is cold. Alwayschange one spark plug at a time. This helps avoid getting the wires mixed up.
1. Remove the center cover on the en-
gine rocker cover (DOHC engine only.)
2. Using a clean cloth, remove any dirt
that has accumulated around the base of the spark plug so it cannot fall into the cylinder when the spark plug is removed.
3. To remove the spark plug cable, pull straight up on the insulated connec-tor, not the cable. Pulling on thecable may damage the carbon core conductor. G060C01A
4. When preparing to remove the oldspark plug, guide the socket downover the spark plug, being careful not to damage the ceramic insula-tor.
5. To remove the old spark plug, turn
the wrench handle in a counter-clockwise direction.

12SPARKING PLUG REPLACEMENT
G060A01L Prior to installing a sparking plug, the gap between the centre and outer elec- trodes must be checked and adjusted as necessary.Adjustment is facilitated by bending the outer electrode towards or away from the centre electrode. Under no circum-stances should attempts be made to adjust the position of the centre elec- trode.
4. Insert the sparking plug into the cyl-
inder head and using a suitable plug socket, slowly rotate the sparkingplug, (being careful not to cross- thread), until the plug contacts the seating area. Tighten the plug withthe plug socket by a further 1/2 to 3/ 4 of a turn only.
3. Clean around the base of the plug to
be removed, and install the plugsocket ensuring that the ceramic insulator does not become damaged.Turn the socket counterclockwise to remove the plug.
CAUTION:
Sparking plugs must only be cleaned using purpose designed equipment.Wire brushing may damage the cen- tre electrode insulator causing mis- firing to occur. Only the correct gradeof sparking plug should be used. Use of an incorrect grade may result in serious engine damage.
!
SG060A1-E (Petrol Engine Only) This operation should only be performed when the engine is cold.
1. Remove the centre cover from the
engine rocker cover (DOHC Engine only).
2. Remove plug lead from the sparking
plug to be replaced, pulling the leadby the rubber cap. (Pulling the lead may damage the carbon conductor.) 0.039~0.043 in. (1.0 ~ 1.1 mm )
