INSTRUCTIONS
Serpent’s long tradition of excellence extends to the instruction manuals, and this instruction manual is no
exception. The easy-to-follow layout is richly illustrated with 3D-rendered full-color images to make your
building experience quick and easy. Following the instructions will result in a well-built, high-performance
race-car that will soon be able to unleash its full potential at the racetrack. The kit includes bags, with
bagnumbers, which refer to the same step in the manual. Open only the indicated bag(s) per step and nish
that part of the assembly. Remaining parts will be needed lateron in the assembly process.
plaSTIC paRTS
The Serpent moulded parts are very durable and hard. When assembling longer screws in new composite
parts, make sure to use new hex bits in your (power) tools. Pre-threading also helps to avoid screw damage.
SETUp
In certain assembly steps you need to make basic adjustments, which will give you a good initial setup for
your Serpent Spyder SDX4. Fine-tuning the initial setup is an essential part of building a high-performance
racecar like your Serpent Spyder SDX4.
