Toro 38621 - Changing the Engine Oil; Inspecting and Replacing the Spark Plug

Changing the Engine Oil
Chang e the engine oil after the first 2 operating hours , then
yearly thereafter . If possible , r un the engine just before
c hanging the oil because w ar m oil flo ws better and car ries
more contaminants .
Max. fill: 26 oz. (0.77 l), type: automoti v e deterg ent oil with

• F or temperatures betw een 0°F and 32°F (-18°C to 0°C),
use SAE 5W30 or SAE 10W .
• F or air temperatures belo w 0°F (-18°C), use SAE 0W30.
1. Clean the area around the oil drain cap ( Figure 42 ).

Lubricating the Hex Shaft
Lightly lubricate the hex shaft yearly with automoti v e engine
oil ( Figure 43 ).

Important: Do not get oil on the r ub ber wheel or
the alumin um friction dri v e plate because the traction
dri v e will slip ( Figur e 43 ).
1. Drain the g asoline from the fuel tank.
2. Tip the sno wthro w er forw ard onto its aug er housing
and bloc k it so that it cannot fall.
3. R emo v e the bac k co v er ( Figure 44 ).

lubricate hex shaft.
6. Mo v e the speed selector lev er to P osition 6.
7. Lubricate the other end of the hex shaft.
8. Mo v e the speed selector lev er forw ard and rearw ard
a few times .
9. Install the bac k co v er and retur n the sno wthro w er to
the operating position.
Inspecting and Replacing the
Spark Plug
Use a Champion RJ-19LM or equi v alent spark plug . Chec k
and g ap the spark yearly , and re place the plug if necessar y .
1. Clean around the base of the spark plug .
2. R emo v e the spark plug .
3. Examine the spark plug and re place it if it is crac k ed,
fouled, dir ty , or if the electrodes are w or n.
Important: Do not clean the electr odes because
g rit could enter the cylinder and dama ge the
engine.
4. Set the g ap betw een the electrodes on the spark plug at
0.030 inc h (0.76 mm) ( Figure 45 ).
