ASSEMBLY AND MAINTENANCE GUIDE

HELPFUL HINTS

✔ Avoid working over a deep pile carpet. If you drop a small part or screw,

it may be diffi cult to fi nd.

✔ Place a mat or towel over your work area. This will prevent parts from rolling off and will protect the work surface.
✔ Avoid running the car in cold weather. The plastic and metal parts can become brittle at low temperatures. In addition, grease and

oil become thick, causing premature wear and poor performance.

MAINTENANCE

BEFORE EACH RUN

✔ IMPORTANT: Check to make sure that all

screws are tight. Check that the servo
saver screw is fully tightened to ensure
that your Dromida SC4.18 tracks straight.

✔ Always check the condition of your

radio system batteries and replace if
necessary.

✔ Check to make sure that all of the

moving parts of the Dromida SC4.18
move freely and do not bind.

✔ Turn on the radio and make sure the

servo moves easily and in the proper
direction.

✔ Check for any broken or damaged

parts. Replace them before running the
Dromida SC4.18. Running the Dromida
SC4.18 with broken or damaged parts
could damage additional parts.

✔ Check to make sure that all wires are

properly connected.

AFTER EACH RUN

✔ Clean any debris from the chassis and

moving parts.

✔ Check for any broken or damaged parts.

Replace them before the next run.

✔ Disconnect and remove the battery

from the chassis.

AFTER EVERY 10 RUNS

✔ Check to make sure that the bearings

are free of dirt and debris, and roll
smoothly.

✔ Check the shocks for oil leakage.
✔ Check the tires to make sure they are

still properly glued to the rims.
